2003-08-19  Gary Thomas  

        * src/stand_alone/eth_drv.c:

        * src/net/eth_drv.c: Improve network speeds by reducing some

        overhead and also the delay when sending a packet.

        * include/eth_drv.h:

        * src/net/eth_drv.c:

        Added an ifndef to fix warnings about NBPFILTER not being

        defined.

2003-03-20  Mark Salter  

        * cdl/eth_drivers.cdl (CYGHWR_NET_DRIVERS): Moved here from net/common.

2003-03-14  Nick Garnett  

        * src/net/eth_drv.c: Added calls to cyg_net_show_mbufs() whenever

        we see an out-of-mbufs problem.

2003-03-11  Mark Salter  

        * src/stand_alone/eth_drv.c (eth_drv_stop): Uncomment, make non-static,

        and use __local_enet_sc.

2003-02-24  Jonathan Larmour  

        * cdl/eth_drivers.cdl: Add doc link.

2003-02-07  Jonathan Larmour

        only a warning.

2002-08-14  Gary Thomas  

        * cdl/eth_drivers.cdl: CYGNUM_IO_ETH_DRIVERS_SG_LIST_SIZE

        needs to be global (used by all drivers, not just NET).

2002-08-13  Gary Thomas  

        * src/net/eth_drv.c (eth_drv_send): Print a better message

        if the scatter-gather list overflows.

        * include/eth_drv.h (MAX_ETH_DRV_SG):

        * cdl/eth_drivers.cdl: Add control over size of scatter-gather

        data lists used to pass requests to physical layer.  Previous

        value was sometimes too small.

2002-07-31  Gary Thomas  

        * src/net/eth_drv.c (eth_drv_start): Fix compile error when

        built with old stack (no multicast) - introduced below.

2002-07-26  Gary Thomas  

2002-07-26  Ken Cox 

        * src/net/eth_drv.c (eth_drv_start): Force multicast address

        setup any time chip is reset/reconfigured.

2002-05-30  Jonathan Larmour  

        * cdl/eth_drivers.cdl: Provide CYGINT_IO_ETH_INT_SUPPORT_REQUIRED

        interface to indicate if interrupt support is required.

2002-05-28  Jonathan Larmour  

        * src/lwip/lw.diff: Remove. Obsolete.

2002-05-13  Jesper Skov  

        * cdl/eth_drivers.cdl: Moved the package's header files to

        cyg/io/eth to clean up the include root directory.

2002-04-30  Jonathan Larmour  

        * src/lwip/eth_drv.c: Update from Jani Monoses.

        * cdl/eth_drivers.cdl: Move CYGINT_ISO_STRING_STRFUNCS requirement

        into CYGPKG_IO_ETH_DRIVERS_NET where it belongs.

        Move CYGINT_ISO_STRING_MEMFUNCS requirement into

        CYGPKG_IO_ETH_DRIVERS_STAND_ALONE where it belongs.

2002-04-10   Gary Thomas 

        * src/net/eth_drv.c: Only pass mutlicast addresses down to drivers.

2002-04-05   Jani Monoses  

        * src/lwip/eth_drv.c: New file. Add eth driver support for lwip.

        * src/lwip/lw.diff: New file. diff against lwip sources.

        * src/lwip/README: New file.

        * cdl/eth_drivers.cdl: Add lwip driver support.

2002-03-09  Gary Thomas  

        * src/net/eth_drv.c: Select 'multicast_all' if too many addresses

        are required.  Also, ignore any non-multicast addresses.

2002-02-22  Hugo Tyson  

        * doc/ethdrv.sgml: New file.  SGML-ized the existing driver-doc

        file and brought the information up to date with deliver functions

        and all that.

2002-02-18  Gary Thomas  

        * cdl/eth_drivers.cdl:

        Add new interface CYGINT_IO_ETH_MULTICAST which is used to

        insure that drivers support multicast addresses if IPv6 is used.

2002-02-15  Gary Thomas  

        * src/net/eth_drv.c:

        * include/eth_drv.h: Add framework for multicast address support.

2002-01-30  Hugo Tyson  

        * cdl/eth_drivers.cdl (CYGPKG_IO_ETH_DRIVERS_WARN_FORCE_CONSOLE):

        CDL options removed; control is now from RedBoot.

        * src/net/eth_drv.c (START_CONSOLE): Changed to use RedBoot

        fconfig items for deciding what console to use for special debug

        messages such as "out of MBUFs" and the like.

        * src/stand_alone/eth_drv.c (LOCK_APPLICATION_SCHEDULER): New

        macro to do what it says, before passing packets to the app.

        Used in two places: when passing a received packet, and when

        passing a tx completion status back.

2002-01-28  Gary Thomas  

        * src/net/eth_drv.c (eth_drv_init): Changes for supporting new

        FreeBSD based stack (minor API changes internal to that stack).

2001-12-12  Hugo Tyson  

        * src/net/eth_drv.c (START_CONSOLE,END_CONSOLE): New macros akin

        to those within RedBoot's internal net_io.c, for directing warning

        messages to a serial line if required.  All printf's wrapped in

        them for safety.

        * cdl/eth_drivers.cdl (CYGPKG_IO_ETH_DRIVERS_WARN_FORCE_CONSOLE):

        and ..._NUMBER, new options to direct application warning output

        somewhere useful (less harmful) for when you are debugging over

        the net.  Trying to print within a call which occurred from within

        RedBoot itself is such a recursive situation as to be fatal.

        Defaults are disabled, you must choose to set these up if

        you want to debug your app safely over the network.

2001-12-12  Hugo Tyson  

        * src/stand_alone/eth_drv.c (DIAG_DUMP_BUF_HDR,DIAG_DUMP_BUF_BDY):

        Separate macros for debug dumps of ethernet header and body.

        (eth_drv_write): Use them.

        (eth_drv_copy_recv): Do not corrupt the static data pointer, so

        that if we are erroneously called twice, at least what we pass is

        a packet, rather than random memory; do not escape to SEGV.  Guard

        against NULL sg_list[].buf pointers, in case caller out of MBUFs.

        (eth_drv_recv): Only dump packet if we actually have a buffer.

        Only forward the packet if actually have a buffer.

2001-12-04  Richard Sandiford  

        * src/stand_alone/eth_drv.c (eth_drv_read): Check that the return

        buffer is big enough to hold the packet.

2001-11-28  Jonathan Larmour  

        * doc/driver_doc: Mention preferences on how the ESA should be set.

2001-10-30  Jonathan Larmour  

        * doc/driver_doc: Add description of poll, deliver and int_vector

        driver functions.

2001-10-29  Hugo Tyson  

        * src/net/eth_drv.c (eth_drv_tickle_devices): [CASE 106613] Rather

        than calling can_send() in the device driver directly, call our

        own eth_drv_send() function which will also dequeue a waiting

        packet if we find we indeed can_send().  This helps to recover

        from queue full situations within the if_ethersubr layer above.

        This change is belt & braces with a similar call in the code which

        drops a packet if the queue is full, in the main network code in

        net/tcpip/.../src/sys/net/if_ethersubr.c (ether_output); this

        change will recover the situation shortly even if the application

        gives up trying to send because of ENOBUFS.

2001-10-18  Jonathan Larmour  

        * cdl/eth_drivers.cdl: Rename CYGSEM_IO_ETH_DRIVERS_DEBUG to

        CYGDBG_IO_ETH_DRIVERS_DEBUG and make it a common option.

        Add separate CYGDBG_IO_ETH_DRIVERS_DEBUG_VERBOSITY config.

        * include/eth_drv.h: Don't claim BSD if it isn't.

        * include/eth_drv_stats.h: Ditto.

        * include/netdev.h: Ditto.

        * src/net/eth_drv.c: Ditto.

        Also use above CDL options to conditionalize debugging (and the

        verbosity level).

        * src/stand_alone/eth_drv.c: Use above renamed CDL options.

2001-10-11  Gary Thomas  

        * src/stand_alone/eth_drv.c (eth_drv_recv):

        Defensive programming - insure valid packet size.

2001-10-05  Jonathan Larmour  

        * src/net/eth_drv.c: Add default implementation of min().

2001-09-26  Jesper Skov  

        * cdl/eth_drivers.cdl: Require the string functions.

        * src/stand_alone/eth_drv.c: Fix warnings.

2001-09-25  Hugo Tyson  

        * src/net/eth_drv.c (eth_drv_dsr): Assert that the "sc" given to

        eth_drv_dsr() really is a sc from the valid list.  This can save a

        few hours debug time of a typo.

2001-09-13  Hugo Tyson  

        * src/net/eth_drv.c (eth_drv_tickle_devices): New function to call

        can_send() on all devices to allow them to unstick from a lost

        interrupt or other wedge - it's up to the device to detect this,

        of course, can_send() does not explicitly do this, it's just used

        as an opportunity harmlessly to get control into the device so it

        can examine its world.

2001-09-05  Gary Thomas  

        * src/stand_alone/eth_drv.c (eth_drv_init): Don't initialize

        structures if ESA is zero.  This is used by low level drivers

        to indicate that a device is present, but can't currently be

        used.  The eCos driver handles this case as well.

2001-08-31  Hugo Tyson  

2001-08-31  Andrew Lunn 

        * src/net/eth_drv.c (eth_drv_tx_done): Guard against a NULL key

        return - which can be caused by race conditions in the driver,

        this is the neatest fixup.  It's good defensive programming

        anyway and ASCOM's tests indicate a benefit for CASE 106059.

2001-08-22  Gary Thomas  

        * src/stand_alone/eth_drv.c:

        printf() is no longer a part of RedBoot.  Thus all programs

        must use diag_printf() and related functions instead.

        * cdl/eth_drivers.cdl: Only enable warning/debug modes if RedBoot

        is present as the debug environment (since there are implicit

        dependencies on RedBoot functions).

2001-08-20  Jonathan Larmour  

        * src/net/eth_drv.c (eth_drv_send): Move endif location to fix build

        error.

2001-08-17  Jonathan Larmour  

        * cdl/eth_drivers.cdl (CYGSEM_IO_ETH_DRIVERS_DEBUG): Now booldata.

        * src/stand_along/eth_drv.c (eth_drv_tx_done): Use different

        value of CYGSEM_IO_ETH_DRIVERS_DEBUG for verbosity.

2001-08-14  Gary Thomas  

        * src/stand_alone/eth_drv.c (eth_drv_write):

        (eth_drv_tx_done):

        (eth_drv_read): Better handling of stacking (layering) of drivers.

        RedBoot (stand alone code) is designed to call into the eCos

        stack and these changes make sure that this is done properly

        nested/stacked.  These changes also affect the behaviour positively

        for CR 902745-CR.

        * src/net/eth_drv.c (eth_drv_send): Add locking of driver while

        actual hardware routines are involved.  Since the same driver

        can be shared by both eCos and RedBoot, it is imperative that

        additional locking (in the form of locking the scheduler) be

        employed during this window to make sure that the hardware is

        handled in complete, consistent steps.  This helps with known

        bug CR 902745-CR.

2001-08-09  Hugo Tyson  

        * src/net/eth_drv.c (eth_drv_recv): Add a pair of

        CYGARC_HAL_SAVE_GP()/CYGARC_HAL_RESTORE_GP() on entry and exit;

        this function is intercalled between RedBoot and the application.

        A minor re-org at the ending to accommodate these macros' nesting.

        (eth_drv_tx_done): CYGARC_HAL_SAVE_GP()/CYGARC_HAL_RESTORE_GP().

        * src/stand_alone/eth_drv.c (eth_drv_tx_done): Add a pair of

        CYGARC_HAL_SAVE_GP()/CYGARC_HAL_RESTORE_GP() on entry and exit;

        this function is intercalled between RedBoot and the application.

        Also make printing message about "tx_done for other key" also

        conditional on net_debug variable - it's commonplace.

        (eth_drv_recv): CYGARC_HAL_SAVE_GP()/CYGARC_HAL_RESTORE_GP().

        (eth_drv_copy_recv): CYGARC_HAL_SAVE_GP()/CYGARC_HAL_RESTORE_GP().

2001-07-03  Gary Thomas  

        * src/net/eth_drv.c (eth_drv_recv): Better cleanup when running

        out of mbufs - could have lost mbufs before.

2001-06-21  David Woodhouse 

        * src/stand_alone/eth_drv.c: Timeout when waiting for Ethernet

        driver to finish sending packet.

        * src/stand_alone/eth_drv.c: Don't delay if it's ready immediately.

2001-06-11  Gary Thomas  

        * cdl/eth_drivers.cdl: Make debug default for RedBoot.

2001-05-22  Jonathan Larmour  

        * cdl/eth_drivers.cdl: New option: CYGSEM_IO_ETH_DRIVERS_PASS_PACKETS

        which replaces the static define in...

        * src/stand_alone_eth_drv.c: Rename ETH_DRV_PASS_PACKETS to

        new CDL option above.

        Also, ensure references to start_console/end_console are conditional

        on CYGSEM_IO_ETH_DRIVERS_DEBUG.

2001-05-22  Hugo Tyson  

2001-05-22  Sanjay Bisen 

        * src/net/eth_drv.c (eth_drv_recv): Patch from Sanjay at Ascom; it

        leaked one mbuf if you run out of clusters.  Fix is simply to

        free m in addition to top.

        * src/net/eth_drv.c (eth_drv_run_deliveries): Fixed a warning with

        an int cast in HAL_CTRLC_CHECK().

2001-03-21  Gary Thomas  

        * cdl/eth_drivers.cdl: Fewer buffers needed in stand-alone mode.

2001-03-12  Hugo Tyson  

        * cdl/eth_drivers.cdl: Permit defines for

        CYGPKG_IO_ETH_DRIVERS_STAND_ALONE and CYGPKG_IO_ETH_DRIVERS_NET.

        The generic i82559 driver needs to know, unfortunately; it calls

        its own DSR directly to unblock after a lost interrupt.  And you

        mustn't call the DSR under RedBoot == ....STAND_ALONE.

2001-01-15  Jesper Skov  

        * src/net/eth_drv.c (eth_drv_init): Do not use enaddr if NULL.

2001-01-07  Gary Thomas  

        * cdl/eth_drivers.cdl: Add interface 'CYGPKG_NET_DRIVER_FRAMEWORK'

        to describe interdependencies between network stack and driver

        framework packages.

2001-01-04  Gary Thomas  

        * src/net/eth_drv.c (eth_drv_tx_done): Update count of Tx packets.

2000-12-11  Gary Thomas  

        * src/net/eth_drv.c (eth_drv_run_deliveries): Support ^C when

        using network based debug channel.

2000-12-02  Gary Thomas  

        * src/stand_alone/eth_drv.c (eth_drv_write): Debug: dump packet

        before calling hardware routine for improved usability.

2000-10-30  Gary Thomas  

        * include/eth_drv.h: Fix compile error in stand-alone mode.

2000-10-17  Hugo Tyson  

2000-10-10  Andrew Lunn 

        * cdl/eth_drivers.cdl: Add configury to disable the warnings about

        out of mbufs for receives.

        * src/net/eth_drv.c: The changes required for the above.

2000-09-28  Hugo Tyson  

        * src/net/eth_drv.c (eth_drv_run_deliveries): Remove race

        condition; a chance to deliver could be delayed until "next time"

        if the DSR snuck in just right.

2000-09-14  Hugo Tyson  

        * cdl/eth_drivers.cdl: Add configury to control new features.  All

        is controlled globally by CYGPKG_IO_ETH_DRIVERS_SIMULATED_FAILURES

        which is by default off, natch.

        * src/net/eth_drv.c (simulate_fail): Implement simulated failures

        in ethernet packet delivery - independent tx and rx dropping and

        rx packet corruption.  Also a "line break" drop-all feature.

2000-09-13  Gary Thomas  

        * src/stand_alone/eth_drv.c: Take out noisy dump when out of buffers.

2000-09-11  Hugo Tyson  

        * src/stand_alone/eth_drv.c (eth_drv_write): If we timeout waiting

        for the write to complete, do reset the vectors to point to the

        application, rather just a bald "return".

2000-09-08  Hugo Tyson  

        * include/netdev.h (NETDEVTAB_ENTRY): Work around feature of new

        version of CYG_HAL_TABLE_ENTRY() whereby no spaces are allowed.

2000-09-07  Jonathan Larmour  

        * include/netdev.h (cyg_netdevtab_entry_t): Correct syntax for

        CYG_HAL_TABLE_TYPE

2000-09-04  Jonathan Larmour  

        * include/netdev.h (cyg_netdevtab_entry_t): Apply CYG_HAL_TABLE_TYPE

2000-09-01  Hugo Tyson  

        * src/stand_alone/eth_drv.c (eth_drv_dsr): New function, never

        called but maybe referenced in stand_alone context, which lets

        redboot work in the new world.

2000-09-01  Hugo Tyson  

        * OVERVIEW: This is part of the change to the network stack to

        greatly reduce latencies both of (other) DSRs and of thread

        scheduling.  All the work that the network stack *and* individual

        ether drivers used to do in DSRs (including alarm callbacks and

        data copies to/from the device memory) is moved into a "fast

        network thread" instead.  It calls a device's "deliver" function

        to do the work that was previously in the DSR.  This is a separate

        thread so that it can be set higher priority than application

        threads in order to minimize packet loss (depending on the

        driver), if required (the application threads presumed to be

        higher priority in turn than the network thread).  A crucial

        consequence of this is that we are no longer locking against DSRs,

        so a plain mutex can be used rather than the global scheduler

        lock, thus simplifying all the splfoo/splx() style functions.

        These changes WILL BREAK individual device drivers until they are

        updated AND the standalone logical ether driver in this component,

        until it is updated also.

        * include/eth_drv.h (ETH_DRV_SC): Add "deliver" entry to struct

        eth_hwr_funs interface record; declare available DSR and flag for

        "needs delivery" in SC status field.

        * src/net/eth_drv.c (eth_drv_run_deliveries): New function,

        performs callbacks to deliver funcs for all devs that want it.

        (eth_drv_dsr): New function, sets flag in sc and calls up to net

        stack to schedule the fast network thread.

        (eth_drv_send): No need to lock scheduler here.

2000-08-29  Gary Thomas  

        * src/stand_alone/eth_drv.c: Use null buffer, (char *)0,

        instead of wasting memory - low level drivers must be designed

        to handle this case.

2000-08-28  Gary Thomas  

        * src/stand_alone/eth_drv.c: Use new configuration parameters.

        * cdl/eth_drivers.cdl: Add new configury to control number of

        internal buffers used by this layer.  Also exposed some of the

        debug flags here.

2000-08-25  Hugo Tyson  

        * include/eth_drv_stats.h (ether_drv_stats): A little further

        diddling; have a bool to say whether the dot3 info is filled in.

2000-08-24  Hugo Tyson  

        * src/net/eth_drv.c (eth_drv_ioctl): Implement ioctl() calls.

        sockio.h numbers SIOCGIFSTATS and SIOCGIFSTATSUD map to

        ETH_DRV_GET_IF_STATS and ETH_DRV_GET_IF_STATS_UD respectively.

        * include/eth_drv.h (ETH_DRV_GET_IF_STATS_UD): Add new device

        interface ioctl() numbers, to get the struct below filled in.

        Also pull in the definition include file (below).

        * include/eth_drv_stats.h (ether_drv_stats): New file: Define

        common structure for ether devices to return stats info to higher

        up, via an ioctl() call.  SNMP uses this.

2000-08-23  Gary Thomas  

        * src/stand_alone/eth_drv.c:

        * include/eth_drv.h: Low level drivers now need to export a

        function which returns the interrupt vector used by that interface.

        This allows outside code to determine this in a portable fashion.

2000-08-16  Gary Thomas  

        * src/stand_alone/eth_drv.c:

        * include/eth_drv.h: Clean up warnings (better protyping).

        * src/stand_alone/eth_drv.c (eth_drv_write): Abandon sending

        packet if device goes not ready for a long time (in some cases,

        this is the only indication that the link is down).

2000-08-07  Gary Thomas  

        * src/net/eth_drv.c (eth_drv_recv): Add safety in case this gets

        called [from stand-alone code] while interface is not up.

        * src/stand_alone/eth_drv.c:

        * include/eth_drv.h: Rework to more fully support mixed stand-alone

        and system (eCos) stacks.

2000-08-03  Gary Thomas  

        * cdl/eth_drivers.cdl: Reparent within I/O, not NET.  This allows

        for stand-alone use as well as support for other stack implementations.

2000-07-28  Hugo Tyson  

        * src/eth_drv.c (eth_drv_recv): Assert that the length we're asked

        to deal with is at least an ether header, and also be defensive in

        any case; discard small packets.  [CASE 104206]

2000-07-26  Gary Thomas  

        * src/eth_drv.c:

        * include/eth_drv.h: Change interfaces used by hardware layer to

        be "soft" (pointers to functions).  This will allow those drivers

        to be shared by applications and the ROM/debug environment.

2000-07-15  Gary Thomas  

        * include/eth_drv.h: Add [initial] extensions to let this

        layer work either in an eCos environment or stand-alone.

2000-07-11  Gary Thomas  

        * include/eth_drv.h: Add minimal PCMCIA support.

        * src/eth_drv.c (eth_drv_netdev): New function - used to find the

        ethernet device info for PCMCIA devices.

2000-06-23  Hugo Tyson  

        * src/eth_drv.c (eth_drv_send): Do not consume an SG entry for

        zero length data; tolerate overflow of the SG.  Before this, pings

        of 6000 bytes crashed the system!

        You can now set net_debug to 2 to get quieter output; 1 gives the

        whole packet dump as before.

        * include/eth_drv.h (MAX_ETH_DRV_SG): Make this 16 so that an MTU

        made of all mbufs will not overflow.

2000-03-28  Gary Thomas  

        * src/eth_drv.c (eth_drv_recv): Tolerate running out of MBUFs

        instead of "panic"ing.

2000-03-08  Gary Thomas  

        * src/eth_drv.c: Add some function [block] comments.

        (eth_drv_send): Use eCos scheduler lock instead of interrupt lock.

2000-03-08  Hugo Tyson  

        * doc/driver_doc: Add some clarification about what's called when,

        proofreading results, shorter lines so I can print it nicely.

2000-03-06  Gary Thomas  

        * src/eth_drv.c:

        * include/eth_drv.h:

        * doc/driver_doc: Remove generic "priv"ate references.

2000-02-29  Gary Thomas  

        * src/eth_drv.c:

        * include/eth_drv.h: New expanded API for hardware drivers.

2000-02-18  Gary Thomas  

        * src/eth_drv.c (eth_drv_send): Disable interrupts while initiating

        the buffer send - avoid a possible race.

2000-02-08  John Dallaway  

        * cdl/eth_drivers.cdl:

        Reparent under CYGPKG_NET and tidy display strings.
