Linus,
this is a resend of the July 2 patch, plus some additional fixes.
The patch against test7-pre2 is at
http://www.uow.edu.au/~andrewm/linux/3c59x.patch
Outstanding problems:
- Very occasional tx timeouts on collisiony 10bT LANs. The driver
recovers OK. dhinds suspects a h/w bug and has a workaround
in 3c575_cb.c beta. We're still trying to reproduce/explain/fix
this for 3c59x.c.
- Timeouts issuing TxReset and RxReset after an APM resume. The
resumes work OK, but this needs to be addressed.
Linux PM seems generally a bit sick at present. Lots of "cs:
socket cff21800 timed out during reset" at startup and resume,
plus a few total system freizures at resume.
Changelog:
LK1.1.7 2 Jul 2000
- The driver wasn't being a good citizen in shared PCI
interrupt situations. Put an explicit test at the start of the
ISR.
- Reset the transmitter when a txReclaim error occurs, as per
the datasheet.
- The driver would crash the machine if ALL 32
dev_alloc_skb()'s failed at initialisation. Now, we return
-ENOMEM and fail the open() if we can't allocate all the skbs.
- The driver would stop receiving and would require ifdown/ifup
if it completely ran out of Rx skbs during operation. (This is
caused by low memory).
Added the rx_oom_timer stuff to start polling once per second
if this happens.
- The spinlocks around the mdio access functions were blocking
interrupts for 300uSecs on a 400MHz machine. So these were made
more granular and were replaced with spin_lock_bh().
- Make the writes to TxFreeThreshold boomerang-only. This
register is reserved on other NICs.
- Added 802.3x MAC-layer flow control support. See
Documentation/networking/vortex.txt.
LK1.1.8 13 Aug 2000
- Don't fail initialisation if request_region() fails. This is
because the PCMCIA code may have already allocated it.
- Added support for 3c556 mini-PCI NICs.
- Fixed EISA initialisation problem
- Renamed MII_XCVR_PWR and EEPROM_230 to align with 3c575_cb
and D. Becker's drivers.
- Changed 3CCFE575CT initialisation to use MII_XCVR_PWR - now
the 575 initialises correctly!
- Added the INVERT_LED_PWR flag. Used it in place of various
open-coded grot.
- Removed all the `extra_reset' cruft which was a semi-solution
to the 3CCFE575CT initialisation problem.
