|
| 31 |
|
|
*
|
| 32 |
|
|
* Tigran Aivazian <tigran@sco.com>: TLan_PciProbe() now uses
|
| 33 |
|
|
* new PCI BIOS interface.
|
| 34 |
|
|
* Alan Cox <alan@redhat.com>: Fixed the out of memory
|
| 35 |
|
|
* handling.
|
| 36 |
|
|
*
|
| 37 |
|
|
* Torben Mathiasen <torben.mathiasen@compaq.com> New Maintainer!
|
| 38 |
|
|
*
|
| 39 |
|
|
* v1.1 Dec 20, 1999 - Removed linux version checking
|
| 40 |
|
|
* Patch from Tigran Aivazian.
|
| 41 |
|
|
* - v1.1 includes Alan's SMP updates.
|
| 42 |
|
|
* - We still have problems on SMP though,
|
| 43 |
|
|
* but I'm looking into that.
|
| 44 |
|
|
*
|
| 45 |
|
|
* v1.2 Jan 02, 2000 - Hopefully fixed the SMP deadlock.
|
| 46 |
|
|
* - Removed dependency of HZ being 100.
|
| 47 |
|
|
* - We now allow higher priority timers to
|
| 48 |
|
|
* overwrite timers like TLAN_TIMER_ACTIVITY
|
| 49 |
|
|
* Patch from John Cagle <john.cagle@compaq.com>.
|
| 50 |
|
|
* - Fixed a few compiler warnings.
|
| 51 |
|
|
*
|
| 52 |
|
|
* v1.3 Feb 04, 2000 - Fixed the remaining HZ issues.
|
| 53 |
|
|
* - Removed call to pci_present().
|
| 54 |
|
|
* - Removed SA_INTERRUPT flag from irq handler.
|
| 55 |
|
|
* - Added __init and __initdata to reduce resisdent
|
| 56 |
|
|
* code size.
|
| 57 |
|
|
* - Driver now uses module_init/module_exit.
|
| 58 |
|
|
* - Rewrote init_module and tlan_probe to
|
| 59 |
|
|
* share a lot more code. We now use tlan_probe
|
| 60 |
|
|
* with builtin and module driver.
|
| 61 |
|
|
* - Driver ported to new net API.
|
| 62 |
|
|
* - tlan.txt has been reworked to reflect current
|
| 63 |
|
|
* driver (almost)
|
| 64 |
|
|
* - Other minor stuff
|
| 65 |
|
|
*
|
| 66 |
|
|
* v1.4 Feb 10, 2000 - Updated with more changes required after Dave's
|
| 67 |
|
|
* network cleanup in 2.3.43pre7 (Tigran & myself)
|
| 68 |
|
|
* - Minor stuff.
|
| 69 |
|
|
*
|
| 70 |
|
|
* v1.5 March 22, 2000 - Fixed another timer bug that would hang the driver
|
| 71 |
|
|
* if no cable/link were present.
|
| 72 |
|
|
* - Cosmetic changes.
|
| 73 |
|
|
* - TODO: Port completely to new PCI/DMA API
|
| 74 |
|
|
* Auto-Neg fallback.
|
| 75 |
|
|
*
|
| 76 |
|
|
* v1.6 April 04, 2000 - Fixed driver support for kernel-parameters. Haven't
|
| 77 |
|
|
* tested it though, as the kernel support is currently
|
| 78 |
|
|
* broken (2.3.99p4p3).
|
| 79 |
|
|
* - Updated tlan.txt accordingly.
|
| 80 |
|
|
* - Adjusted minimum/maximum frame length.
|
| 81 |
|
|
* - There is now a TLAN website up at
|
| 82 |
|
|
* http://tlan.kernel.dk
|
| 83 |
|
|
*
|
| 84 |
|
|
* v1.7 April 07, 2000 - Started to implement custom ioctls. Driver now
|
| 85 |
|
|
* reports PHY information when used with Donald
|
| 86 |
|
|
* Beckers userspace MII diagnostics utility.
|
| 87 |
|
|
*
|
| 88 |
|
|
* v1.8 April 23, 2000 - Fixed support for forced speed/duplex settings.
|
| 89 |
|
|
* - Added link information to Auto-Neg and forced
|
| 90 |
|
|
* modes. When NIC operates with auto-neg the driver
|
| 91 |
|
|
* will report Link speed & duplex modes as well as
|
| 92 |
|
|
* link partner abilities. When forced link is used,
|
| 93 |
|
|
* the driver will report status of the established
|
| 94 |
|
|
* link.
|
| 95 |
|
|
* Please read tlan.txt for additional information.
|
| 96 |
|
|
* - Removed call to check_region(), and used
|
| 97 |
|
|
* return value of request_region() instead.
|
| 98 |
|
|
*
|
| 99 |
|
|
* v1.8a May 28, 2000 - Minor updates.
|
| 100 |
|
|
*
|
| 101 |
|
|
* v1.9 July 25, 2000 - Fixed a few remaining Full-Duplex issues.
|
| 102 |
|
|
* - Updated with timer fixes from Andrew Morton.
|
| 103 |
|
|
* - Fixed module race in TLan_Open.
|
| 104 |
|
|
* - Added routine to monitor PHY status.
|
| 105 |
|
|
* - Added activity led support for Proliant devices.
|
| 106 |
|
|
*
|
| 107 |
|
|
* v1.10 Aug 30, 2000 - Added support for EISA based tlan controllers
|
| 108 |
|
|
* like the Compaq NetFlex3/E.
|
| 109 |
|
|
* - Rewrote tlan_probe to better handle multiple
|
| 110 |
|
|
* bus probes. Probing and device setup is now
|
| 111 |
|
|
* done through TLan_Probe and TLan_init_one. Actual
|
| 112 |
|
|
* hardware probe is done with kernel API and
|
| 113 |
|
|
* TLan_EisaProbe.
|
| 114 |
|
|
* - Adjusted debug information for probing.
|
| 115 |
|
|
* - Fixed bug that would cause general debug information
|
| 116 |
|
|
* to be printed after driver removal.
|
| 117 |
|
|
* - Added transmit timeout handling.
|
| 118 |
|
|
* - Fixed OOM return values in tlan_probe.
|
| 119 |
|
|
* - Fixed possible mem leak in tlan_exit
|
| 120 |
|
|
* (now tlan_remove_one).
|
| 121 |
|
|
* - Fixed timer bug in TLan_phyMonitor.
|
| 122 |
|
|
* - This driver version is alpha quality, please
|
| 123 |
|
|
* send me any bug issues you may encounter.
|
| 124 |
|
|
*
|
| 125 |
|
|
* v1.11 Aug 31, 2000 - Do not try to register irq 0 if no irq line was
|
| 126 |
|
|
* set for EISA cards.
|
| 127 |
|
|
* - Added support for NetFlex3/E with nibble-rate
|
| 128 |
|
|
* 10Base-T PHY. This is untestet as I haven't got
|
| 129 |
|
|
* one of these cards.
|
| 130 |
|
|
* - Fixed timer being added twice.
|
| 131 |
|
|
* - Disabled PhyMonitoring by default as this is
|
| 132 |
|
|
* work in progress. Define MONITOR to enable it.
|
| 133 |
|
|
* - Now we don't display link info with PHYs that
|
| 134 |
|
|
* doesn't support it (level1).
|
| 135 |
|
|
* - Incresed tx_timeout beacuse of auto-neg.
|
| 136 |
|
|
* - Adjusted timers for forced speeds.
|
| 137 |
|
|
*
|
| 138 |
|
|
* v1.12 Oct 12, 2000 - Minor fixes (memleak, init, etc.)
|
| 139 |
|
|
*
|
| 140 |
|
|
* v1.13 Nov 28, 2000 - Stop flooding console with auto-neg issues
|
| 141 |
|
|
* when link can't be established.
|
| 142 |
|
|
* - Added the bbuf option as a kernel parameter.
|
| 143 |
|
|
* - Fixed ioaddr probe bug.
|
| 144 |
|
|
* - Fixed stupid deadlock with MII interrupts.
|
| 145 |
|
|
* - Added support for speed/duplex selection with
|
| 146 |
|
|
* multiple nics.
|
| 147 |
|
|
* - Added partly fix for TX Channel lockup with
|
| 148 |
|
|
* TLAN v1.0 silicon. This needs to be investigated
|
| 149 |
|
|
* further.
|
| 150 |
|
|
*
|
| 151 |
|
|
* v1.14 Dec 16, 2000 - Added support for servicing multiple frames per.
|
| 152 |
|
|
* interrupt. Thanks goes to
|

|
* Denis Beaudoin <dbeaudoin@ti.com>
|
| 155 |
|
|
* for providing the patch.
|
| 156 |
|
|
* - Fixed auto-neg output when using multiple
|
| 157 |
|
|
* adapters.
|
| 158 |
|
|
* - Converted to use new taskq interface.
|
| 159 |
|
|
*
|
| 160 |
|
|
* v1.14a Jan 6, 2001 - Minor adjustments (spinlocks, etc.)

| 161 |
|
|
*
|
| 162 |
|
|
* Samuel Chessman <chessman@tux.org> New Maintainer!
|
| 163 |
|
|
*
|
| 164 |
|
|
* v1.15 Apr 4, 2002 - Correct operation when aui=1 to be
|
| 165 |

|

|
| 1846 |
|
|
* 2 1/2 seconds before attempting to transmit a
|

* PHY.
|
| 1853 |
|
|
* - The ACT LED, which shows adapter activity, is
|
| 1854 |
|
|
* driven by the driver, and so must be left on
|
| 1855 |
|
|
* for a short period to power up the LED so it
|
| 1856 |
