2003-10-09  Gary Thomas  
56
 
57

60
2003-08-19  Gary Thomas  
61
 
62
        * src/stand_alone/eth_drv.c:
63
        * src/net/eth_drv.c: Improve network speeds by reducing some

67
 
68
        * include/eth_drv.h:

81
 
82
2003-03-11  Mark Salter  
83
 
84
        * src/stand_alone/eth_drv.c (eth_drv_stop): Uncomment, make non-static,

87
 
88
2003-02-24  Jonathan Larmour  
89

        * cdl/eth_drivers.cdl: Add doc link.
91
 
92
2003-02-07  Jonathan Larmour  
93
 
94
        * src/net/eth_drv.c: If driver can't set multi-cast, indicate it's
95
        only a warning.
96
 
97
2002-08-14  Gary Thomas  
98
 
99
        * cdl/eth_drivers.cdl: CYGNUM_IO_ETH_DRIVERS_SG_LIST_SIZE
100
        needs to be global (used by all drivers, not just NET).
101
 
102
2002-08-13  Gary Thomas  
103
 
104
        * src/net/eth_drv.c (eth_drv_send): Print a better message
105
        if the scatter-gather list overflows.
106
 
107
        * include/eth_drv.h (MAX_ETH_DRV_SG):
108
        * cdl/eth_drivers.cdl: Add control over size of scatter-gather
109
        data lists used to pass requests to physical layer.  Previous
110
        value was sometimes too small.
111
 
112
2002-07-31  Gary Thomas  
113
 
114
        * src/net/eth_drv.c (eth_drv_start): Fix compile error when
115
        built with old stack (no multicast) - introduced below.
116
 
117
2002-07-26  Gary Thomas  
118
2002-07-26  Ken Cox 
119
 
120
        * src/net/eth_drv.c (eth_drv_start): Force multicast address

122
 
123
2002-05-30  Jonathan Larmour  
124
 
125
        * cdl/eth_drivers.cdl: Provide CYGINT_IO_ETH_INT_SUPPORT_REQUIRED
126
        interface to indicate if interrupt support is required.
127
 
128
2002-05-28  Jonathan Larmour  
129
 
130
        * src/lwip/lw.diff: Remove. Obsolete.
131
 
132
2002-05-13  Jesper Skov  
133
 
134
        * cdl/eth_drivers.cdl: Moved the package's header files to
135
        cyg/io/eth to clean up the include root directory.
136
 
137
2002-04-30  Jonathan Larmour

        * cdl/eth_drivers.cdl: Move CYGINT_ISO_STRING_STRFUNCS requirement
142
        into CYGPKG_IO_ETH_DRIVERS_NET where it belongs.
143
        Move CYGINT_ISO_STRING_MEMFUNCS requirement into
144
        CYGPKG_IO_ETH_DRIVERS_STAND_ALONE where it belongs.
145
 
146
2002-04-10   Gary Thomas 
147
 
148
        * src/net/eth_drv.c: Only pass mutlicast addresses down to drivers.
149
 
150
2002-04-05   Jani Monoses  
151
 
152
        * src/lwip/eth_drv.c: New file. Add eth driver support for lwip.
153
        * src/lwip/lw.diff: New file. diff against lwip sources.
154
        * src/lwip/README: New file.
155
        * cdl/eth_drivers.cdl: Add lwip driver support.
156
 
157
2002-03-09  Gary Thomas  
158
 
159
        * src/net/eth_drv.c: Select 'multicast_all' if too many addresses
160
        are required.  Also, ignore any non-multicast addresses.
161
 
162
2002-02-22  Hugo Tyson  
163
 
164
        * doc/ethdrv.sgml: New file.  SGML-ized the existing driver-doc
165
        file and brought the information up to date with deliver functions
166
        and all that.
167
 
168
2002-02-18  Gary Thomas  
169
 
170
        * cdl/eth_drivers.cdl:
171
        Add new interface CYGINT_IO_ETH_MULTICAST which is used to
172
        insure that drivers support multicast addresses if IPv6 is used.
173
 
174
2002-02-15  Gary Thomas  
175
 
176
        * src/net/eth_drv.c:
177
        * include/eth_drv.h: Add framework for multicast address support.
178
 
179
2002-01-30  Hugo Tyson  
180
 
181
        * cdl/eth_drivers.cdl (CYGPKG_IO_ETH_DRIVERS_WARN_FORCE_CONSOLE):
182
        CDL options removed; control is now from RedBoot.
183
 
184
        * src/net/eth_drv.c (START_CONSOLE): Changed to use RedBoot
185
        fconfig items for deciding what console to use for special debug
186
        messages such as "out of MBUFs" and the like.
187
 
188
        * src/stand_alone/eth_drv.c (LOCK_APPLICATION_SCHEDULER): New
189
        macro to do what it says, before passing packets to the app.
190
        Used in two places: when passing a received packet, and when
191
        passing a tx completion status back.
192
 
193
2002-01-28  Gary Thomas  
194
 
195
        * src/net/eth_drv.c (eth_drv_init): Changes for supporting new
196
        FreeBSD based stack (minor API changes internal to that stack).
197
 
198
2001-12-12  Hugo Tyson  
199
 
200
        * src/net/eth_drv.c (START_CONSOLE,END_CONSOLE): New macros akin
201
        to those within RedBoot's internal net_io.c, for directing warning
202
        messages to a serial line if required.  All printf's wrapped in
203
        them for safety.
204
 
205
        * cdl/eth_drivers.cdl (CYGPKG_IO_ETH_DRIVERS_WARN_FORCE_CONSOLE):
206
        and ..._NUMBER, new options to direct application warning output
207
        somewhere useful (less harmful) for when you are debugging over
208
        the net.  Trying to print within a call which occurred from within
209
        RedBoot itself is such a recursive situation as to be fatal.
210
        Defaults are disabled, you must choose to set these up if
211
        you want to debug your app safely over the network.
212
 
213
2001-12-12  Hugo Tyson  
214
 
215
        * src/stand_alone/eth_drv.c (DIAG_DUMP_BUF_HDR,DIAG_DUMP_BUF_BDY):
216
        Separate macros for debug dumps of ethernet header and body.
217
        (eth_drv_write): Use them.
218
        (eth_drv_copy_recv): Do not corrupt the static data pointer, so
219
        that if we are erroneously called twice, at least what we pass is
220
        a packet, rather than random memory; do not escape to SEGV.  Guard
221
        against NULL sg_list[].buf pointers, in case caller out of MBUFs.
222
        (eth_drv_recv): Only dump packet if we actually have a buffer.
223
        Only forward the packet if actually have a buffer.
224
 
225
2001-12-04  Richard Sandiford  
226
 
227
        * src/stand_alone/eth_drv.c (eth_drv_read): Check that the return
228
        buffer is big enough to hold the packet.
229
 
230
2001-11-28  Jonathan Larmour  
231
 
232
        * doc/driver_doc: Mention preferences on how the ESA should be set.
233
 
234
2001-10-30  Jonathan Larmour  
235
 
236
        * doc/driver_doc: Add description of poll, deliver and int_vector
237
        driver functions.
238
 
239
2001-10-29  Hugo Tyson  
240
 
241
        * src/net/eth_drv.c (eth_drv_tickle_devices): [CASE 106613] Rather
242
        than calling can_send() in the device driver directly, call our
243
        own eth_drv_send() function which will also dequeue a waiting
244
        packet if we find we indeed can_send().  This helps to recover
245
        from queue full situations within the if_ethersubr layer above.
246
        This change is belt & braces with a similar call in the code which
247
        drops a packet if the queue is full, in the main network code in
248
        net/tcpip/.../src/sys/net/if_ethersubr.c (ether_output); this
249
        change will recover the situation shortly even if the application
250
        gives up trying to send because of ENOBUFS.
251
 
252
2001-10-18  Jonathan Larmour  
253
 
254
        * cdl/eth_drivers.cdl: Rename CYGSEM_IO_ETH_DRIVERS_DEBUG to
255
        CYGDBG_IO_ETH_DRIVERS_DEBUG and make it a common option.
256
        Add separate CYGDBG_IO_ETH_DRIVERS_DEBUG_VERBOSITY config.
257
 
258
        * include/eth_drv.h: Don't claim BSD if it isn't.
259
        * include/eth_drv_stats.h: Ditto.
260
        * include/netdev.h: Ditto.
261
        * src/net/eth_drv.c: Ditto.
262
        Also use above CDL options to conditionalize debugging (and the
263
        verbosity level).
264
        * src/stand_alone/eth_drv.c: Use above renamed CDL options.
265
 
266
2001-10-11  Gary Thomas  
267
 
268
        * src/stand_alone/eth_drv.c (eth_drv_recv):
269
        Defensive programming - insure valid packet size.
270
 
271
2001-10-05  Jonathan Larmour  
272
 
273
        * src/net/eth_drv.c: Add default implementation of min().
274
 
275
2001-09-26  Jesper Skov  
276
 
277
        * cdl/eth_drivers.cdl: Require the string functions.
278
 
279
        * src/stand_alone/eth_drv.c: Fix warnings.
280
 
281
2001-09-25  Hugo Tyson  
282
 
283
        * src/net/eth_drv.c (eth_drv_dsr): Assert that the "sc" given to
284
        eth_drv_dsr() really is a sc from the valid list.  This can save a
285
        few hours debug time of a typo.
286
 
287
2001-09-13  Hugo Tyson  
288
 
289
        * src/net/eth_drv.c (eth_drv_tickle_devices): New function to call
290
        can_send() on all devices to allow them to unstick from a lost
291
        interrupt or other wedge - it's up to the device to detect this,
292
        of course, can_send() does not explicitly do this, it's just used
293
        as an opportunity harmlessly to get control into the device so it
294
        can examine its world.
295
 
296
2001-09-05  Gary Thomas  
297
 
298
        * src/stand_alone/eth_drv.c (eth_drv_init): Don't initialize
299
        structures if ESA is zero.  This is used by low level drivers
300
        to indicate that a device is present, but can't currently be
301
        used.  The eCos driver handles this case as well.
302
 
303
2001-08-31  Hugo Tyson  
304
2001-08-31  Andrew Lunn 
305
 
306
        * src/net/eth_drv.c (eth_drv_tx_done): Guard against a NULL key
307
        return - which can be caused by race conditions in the driver,
308
        this is the neatest fixup.  It's good defensive programming
309
        anyway and ASCOM's tests indicate a benefit for CASE 106059.
310
 
311
2001-08-22  Gary Thomas  
312
 
313
        * src/stand_alone/eth_drv.c:
314
        printf() is no longer a part of RedBoot.  Thus all programs
315
        must use diag_printf() and related functions instead.
316
 
317
        * cdl/eth_drivers.cdl: Only enable warning/debug modes if RedBoot
318
        is present as the debug environment (since there are implicit
319
        dependencies on RedBoot functions).
320
 
321
2001-08-20  Jonathan Larmour  
322
 
323
        * src/net/eth_drv.c (eth_drv_send): Move endif location to fix build
324
        error.
325
 
326
2001-08-17  Jonathan Larmour  
327
 
328
        * cdl/eth_drivers.cdl (CYGSEM_IO_ETH_DRIVERS_DEBUG): Now booldata.
329
        * src/stand_along/eth_drv.c (eth_drv_tx_done): Use different
330
        value of CYGSEM_IO_ETH_DRIVERS_DEBUG for verbosity.
331
 
332
2001-08-14  Gary Thomas  
333
 
334
        * src/stand_alone/eth_drv.c (eth_drv_write):
335
        (eth_drv_tx_done):
336
        (eth_drv_read): Better handling of stacking (layering) of drivers.
337
        RedBoot (stand alone code) is designed to call into the eCos
338
        stack and these changes make sure that this is done properly
339
        nested/stacked.  These changes also affect the behaviour positively
340
        for CR 902745-CR.
341
 
342
        * src/net/eth_drv.c (eth_drv_send): Add locking of driver while
343
        actual hardware routines are involved.  Since the same driver
344
        can be shared by both eCos and RedBoot, it is imperative that
345
        additional locking (in the form of locking the scheduler) be
346
        employed during this window to make sure that the hardware is
347
        handled in complete, consistent steps.  This helps with known
348
        bug CR 902745-CR.
349
 
350
2001-08-09  Hugo Tyson  
351
 
352
        * src/net/eth_drv.c (eth_drv_recv): Add a pair of
353
        CYGARC_HAL_SAVE_GP()/CYGARC_HAL_RESTORE_GP() on entry and exit;
354
        this function is intercalled between RedBoot and the application.
355
        A minor re-org at the ending to accommodate these macros' nesting.
356
        (eth_drv_tx_done): CYGARC_HAL_SAVE_GP()/CYGARC_HAL_RESTORE_GP().
357
 
358
        * src/stand_alone/eth_drv.c (eth_drv_tx_done): Add a pair of
359
        CYGARC_HAL_SAVE_GP()/CYGARC_HAL_RESTORE_GP() on entry and exit;
360
        this function is intercalled between RedBoot and the application.
361
        Also make printing message about "tx_done for other key" also
362
        conditional on net_debug variable - it's commonplace.
363
        (eth_drv_recv): CYGARC_HAL_SAVE_GP()/CYGARC_HAL_RESTORE_GP().
364
        (eth_drv_copy_recv): CYGARC_HAL_SAVE_GP()/CYGARC_HAL_RESTORE_GP().

366
2001-07-03  Gary Thomas  
367
 
368
        * src/net/eth_drv.c (eth_drv_recv): Better cleanup when running
369
        out of mbufs - could have lost mbufs before.
370
 
371
2001-06-21  David Woodhouse 
372
 
373
        * src/stand_alone/eth_drv.c: Timeout when waiting for Ethernet
374
        driver to finish sending packet.
375
        * src/stand_alone/eth_drv.c: Don't delay if it's ready immediately.
376
 
377
2001-06-11  Gary Thomas  
378
 
379
        * cdl/eth_drivers.cdl: Make debug default for RedBoot.
380
 
381
2001-05-22  Jonathan Larmour  
382
 
383
        * cdl/eth_drivers.cdl: New option: CYGSEM_IO_ETH_DRIVERS_PASS_PACKETS
384
        which replaces the static define in...
385
        * src/stand_alone_eth_drv.c: Rename ETH_DRV_PASS_PACKETS to
386
        new CDL option above.
387
        Also, ensure references to start_console/end_console are conditional
388
        on CYGSEM_IO_ETH_DRIVERS_DEBUG.

2001-05-22  Hugo Tyson  
391
2001-05-22  Sanjay Bisen 
392
 
393
        * src/net/eth_drv.c (eth_drv_recv): Patch from Sanjay at Ascom; it
394
        leaked one mbuf if you run out of clusters.  Fix is simply to
395
        free m in addition to top.
396
 
397
        * src/net/eth_drv.c (eth_drv_run_deliveries): Fixed a warning with
398
        an int cast in HAL_CTRLC_CHECK().
399
 
400
2001-03-21  Gary Thomas  
401
 
402
        * cdl/eth_drivers.cdl: Fewer buffers needed in stand-alone mode.
403
 
404
2001-03-12  Hugo Tyson  
405
 
406
        * cdl/eth_drivers.cdl: Permit defines for
407
        CYGPKG_IO_ETH_DRIVERS_STAND_ALONE and CYGPKG_IO_ETH_DRIVERS_NET.
408
        The generic i82559 driver needs to know, unfortunately; it calls
409
        its own DSR directly to unblock after a lost interrupt.  And you
410
        mustn't call the DSR under RedBoot == ....STAND_ALONE.
411
 
412
2001-01-15  Jesper Skov  
413
 
414
        * src/net/eth_drv.c (eth_drv_init): Do not use enaddr if NULL.
415
 
416
2001-01-07  Gary Thomas  
417
 
418
        * cdl/eth_drivers.cdl: Add interface 'CYGPKG_NET_DRIVER_FRAMEWORK'
419
        to describe interdependencies between network stack and driver
420
        framework packages.
421
 
422
2001-01-04  Gary Thomas  
423
 
424
        * src/net/eth_drv.c (eth_drv_tx_done): Update count of Tx packets.
425
 
426
2000-12-11  Gary Thomas  
427
 
428
        * src/net/eth_drv.c (eth_drv_run_deliveries): Support ^C when
429
        using network based debug channel.
430
 
431
2000-12-02  Gary Thomas  
432
 
433
        * src/stand_alone/eth_drv.c (eth_drv_write): Debug: dump packet
434
        before calling hardware routine for improved usability.
435
 
436
2000-10-30  Gary Thomas  
437
 
438
        * include/eth_drv.h: Fix compile error in stand-alone mode.
439
 
440
2000-10-17  Hugo Tyson  
441
2000-10-10  Andrew Lunn 
442
        * cdl/eth_drivers.cdl: Add configury to disable the warnings about
443
        out of mbufs for receives.
444
 
445
        * src/net/eth_drv.c: The changes required for the above.
446
 
447
2000-09-28  Hugo Tyson  
448
 
449
        * src/net/eth_drv.c (eth_drv_run_deliveries): Remove race
450
        condition; a chance to deliver could be delayed until "next time"
451
        if the DSR snuck in just right.
452
 
453
2000-09-14  Hugo Tyson  
454
 
455
        * cdl/eth_drivers.cdl: Add configury to control new features.  All
456
        is controlled globally by CYGPKG_IO_ETH_DRIVERS_SIMULATED_FAILURES
457
        which is by default off, natch.
458
 
459
        * src/net/eth_drv.c (simulate_fail): Implement simulated failures
460
        in ethernet packet delivery - independent tx and rx dropping and
461
        rx packet corruption.  Also a "line break" drop-all feature.
462
 
463
2000-09-13  Gary Thomas  
464
 
465
        * src/stand_alone/eth_drv.c: Take out noisy dump when out of buffers.
466
 
467
2000-09-11  Hugo Tyson  
468
 
469
        * src/stand_alone/eth_drv.c (eth_drv_write): If we timeout waiting
470
        for the write to complete, do reset the vectors to point to the
471
        application, rather just a bald "return".
472
 
473
2000-09-08  Hugo Tyson  
474
 
475
        * include/netdev.h (NETDEVTAB_ENTRY): Work around feature of new
476
        version of CYG_HAL_TABLE_ENTRY() whereby no spaces are allowed.
477
 
478
2000-09-07  Jonathan Larmour  
479
 
480
        * include/netdev.h (cyg_netdevtab_entry_t): Correct syntax for
481
        CYG_HAL_TABLE_TYPE
482
 
483
2000-09-04  Jonathan Larmour  
484
 
485
        * include/netdev.h (cyg_netdevtab_entry_t): Apply CYG_HAL_TABLE_TYPE
486
 
487
2000-09-01  Hugo Tyson  
488
 
489
        * src/stand_alone/eth_drv.c (eth_drv_dsr): New function, never
490
        called but maybe referenced in stand_alone context, which lets
491
        redboot work in the new world.
492
 
493
2000-09-01  Hugo Tyson  
494
 
495
        * OVERVIEW: This is part of the change to the network stack to
496
        greatly reduce latencies both of (other) DSRs and of thread
497
        scheduling.  All the work that the network stack *and* individual
498
        ether drivers used to do in DSRs (including alarm callbacks and
499
        data copies to/from the device memory) is moved into a "fast
500
        network thread" instead.  It calls a device's "deliver" function
501
        to do the work that was previously in the DSR.  This is a separate
502
        thread so that it can be set higher priority than application
503
        threads in order to minimize packet loss (depending on the
504
        driver), if required (the application threads presumed to be
505
        higher priority in turn than the network thread).  A crucial
506
        consequence of this is that we are no longer locking against DSRs,
507
        so a plain mutex can be used rather than the global scheduler
508
        lock, thus simplifying all the splfoo/splx() style functions.
509
 
510
        These changes WILL BREAK individual device drivers until they are
511
        updated AND the standalone logical ether driver in this component,
512
        until it is updated also.
513
 
514
        * include/eth_drv.h (ETH_DRV_SC): Add "deliver" entry to struct
515
        eth_hwr_funs interface record; declare available DSR and flag for
516
        "needs delivery" in SC status field.
517
 
518
        * src/net/eth_drv.c (eth_drv_run_deliveries): New function,
519
        performs callbacks to deliver funcs for all devs that want it.
520
        (eth_drv_dsr): New function, sets flag in sc and calls up to net
521
        stack to schedule the fast network thread.
522
        (eth_drv_send): No need to lock scheduler here.
523
 
524
2000-08-29  Gary Thomas  
525
 
526
        * src/stand_alone/eth_drv.c: Use null buffer, (char *)0,
527
        instead of wasting memory - low level drivers must be designed
528
        to handle this case.
529
 
530
2000-08-28  Gary Thomas  
531
 
532
        * src/stand_alone/eth_drv.c: Use new configuration parameters.
533
 
534
        * cdl/eth_drivers.cdl: Add new configury to control number of
535
        internal buffers used by this layer.  Also exposed some of the
536
        debug flags here.
537
 
538
2000-08-25  Hugo Tyson  
539
 
540
        * include/eth_drv_stats.h (ether_drv_stats): A little further
541
        diddling; have a bool to say whether the dot3 info is filled in.
542
 
543
2000-08-24  Hugo Tyson  
544
 
545
        * src/net/eth_drv.c (eth_drv_ioctl): Implement ioctl() calls.
546
        sockio.h numbers SIOCGIFSTATS and SIOCGIFSTATSUD map to
547
        ETH_DRV_GET_IF_STATS and ETH_DRV_GET_IF_STATS_UD respectively.
548
 
549
        * include/eth_drv.h (ETH_DRV_GET_IF_STATS_UD): Add new device
550
        interface ioctl() numbers, to get the struct below filled in.
551
        Also pull in the definition include file (below).
552
 
553
        * include/eth_drv_stats.h (ether_drv_stats): New file: Define
554
        common structure for ether devices to return stats info to higher
555
        up, via an ioctl() call.  SNMP uses this.
556
 
557
2000-08-23  Gary Thomas  
558
 
559
        * src/stand_alone/eth_drv.c:
560
        * include/eth_drv.h: Low level drivers now need to export a
561
        function which returns the interrupt vector used by that interface.
562
        This allows outside code to determine this in a portable fashion.
563
 
564
2000-08-16  Gary Thomas  
565
 
566
        * src/stand_alone/eth_drv.c:
567
        * include/eth_drv.h: Clean up warnings (better protyping).
568
 
569
        * src/stand_alone/eth_drv.c (eth_drv_write): Abandon sending
570
        packet if device goes not ready for a long time (in some cases,
571
        this is the only indication that the link is down).
572
 
573
2000-08-07  Gary Thomas  
574
 
575
        * src/net/eth_drv.c (eth_drv_recv): Add safety in case this gets
576
        called [from stand-alone code] while interface is not up.
577
 
578
        * src/stand_alone/eth_drv.c:
579
        * include/eth_drv.h: Rework to more fully support mixed stand-alone
580
        and system (eCos) stacks.
581
 
582
2000-08-03  Gary Thomas  
583
 
584
        * cdl/eth_drivers.cdl: Reparent within I/O, not NET.  This allows
585
        for stand-alone use as well as support for other stack implementations.
586
 
587
2000-07-28  Hugo Tyson  
588
 
589
        * src/eth_drv.c (eth_drv_recv): Assert that the length we're asked
590
        to deal with is at least an ether header, and also be defensive in
591
        any case; discard small packets.  [CASE 104206]
592
 
593
2000-07-26  Gary Thomas  
594
 
595
        * src/eth_drv.c:
596
        * include/eth_drv.h: Change interfaces used by hardware layer to
597
        be "soft" (pointers to functions).  This will allow those drivers
598
        to be shared by applications and the ROM/debug environment.
599
 
600
2000-07-15  Gary Thomas  
601
 
602
        * include/eth_drv.h: Add [initial] extensions to let this
603
        layer work either in an eCos environment or stand-alone.
604
 
605
2000-07-11  Gary Thomas  
606
 
607
        * include/eth_drv.h: Add minimal PCMCIA support.
608
 
609
        * src/eth_drv.c (eth_drv_netdev): New function - used to find the
610
        ethernet device info for PCMCIA devices.
611
 
612
2000-06-23  Hugo Tyson  
613
 
614
        * src/eth_drv.c (eth_drv_send): Do not consume an SG entry for
615
        zero length data; tolerate overflow of the SG.  Before this, pings
616
        of 6000 bytes crashed the system!
617
 
618
        You can now set net_debug to 2 to get quieter output; 1 gives the
619
        whole packet dump as before.
620
 
621
        * include/eth_drv.h (MAX_ETH_DRV_SG): Make this 16 so that an MTU
622
        made of all mbufs will not overflow.
623
 
624
2000-03-28  Gary Thomas  
625
 
626
        * src/eth_drv.c (eth_drv_recv): Tolerate running out of MBUFs
627
        instead of "panic"ing.
628
 
629
2000-03-08  Gary Thomas  
630
 
631
        * src/eth_drv.c: Add some function [block] comments.
632
        (eth_drv_send): Use eCos scheduler lock instead of interrupt lock.
633
 
634
2000-03-08  Hugo Tyson  
635
 
636
        * doc/driver_doc: Add some clarification about what's called when,
637
        proofreading results, shorter lines so I can print it nicely.
638
 
639
2000-03-06  Gary Thomas  
640
 
641
        * src/eth_drv.c:
642
        * include/eth_drv.h:
643
        * doc/driver_doc: Remove generic "priv"ate references.
644
 
645
2000-02-29  Gary Thomas  
646
 
647
        * src/eth_drv.c:
648
        * include/eth_drv.h: New expanded API for hardware drivers.
649
 
650
2000-02-18  Gary Thomas  
651
 
652
        * src/eth_drv.c (eth_drv_send): Disable interrupts while initiating
653
        the buffer send - avoid a possible race.
654
 
655
2000-02-08  John Dallaway  
656
 
657
        * cdl/eth_drivers.cdl:
658
        Reparent under CYGPKG_NET and tidy display strings.
