bad news. I today tried the sky2 driver which is in Linus Kernel Tree
(HEAD) on a machine with very high network load and it stopped working
without any kernel messages after doing a flawless job under high load
for 5 hours. My watchdog rebooted the machine after 500 seconds. ;-(

I have run for 2+ days under load without problems. It is hard to
reproduce or do much about your problem without more info.

Are there some debug hooks that can be activated?  My sky2 stops
responding (very light load) about twice a day.  The netdev watchdog
notices after a while and is able to reactivate the interface:

Mar 15 13:28:12 btd kernel: NETDEV WATCHDOG: eth0: transmit timed out
Mar 15 13:28:12 btd kernel: sky2 eth0: tx timeout
Mar 15 13:28:12 btd kernel: sky2 eth0: transmit ring 458 .. 435 report=458 done=458
Mar 15 13:28:12 btd kernel: sky2 eth0: disabling interface
Mar 15 13:28:12 btd kernel: sky2 eth0: enabling interface
Mar 15 13:28:12 btd kernel: sky2 eth0: ram buffer 48K
Mar 15 13:28:15 btd kernel: sky2 eth0: Link is up at 1000 Mbps, full duplex, flow control both

This machine is a Core2 Duo e6700, and the interface is:
03:00.0 Ethernet controller: Marvell Technology Group Ltd. 88E8053 PCI-E Gigabit Ethernet Controller (rev 20)
to 1 Gb hub.

On a Pentium 4, with:
02:00.0 Ethernet controller: Marvell Technology Group Ltd. 88E8053 PCI-E Gigabit Ethernet Controller (rev 15)
I have no issues, but with a very light network load, 100 Mb/s hub..

Each machine has two identical interfaces; only one has a cable in it.

Both machines can be used for testing/debug.

Use ethtool -S to if there are any pause frames, etc. See if frames are
still making it into PHY statistics but not being received.

Use ethtool -d to dump registers. Need current version of ethtool with decode logic.

Then look for things like is Ram buffer read/write pointer changing?

Is GMAC stuck in pause:

Normal is:
	GMAC 1
	Status                       0x5010  (see GM_GPSR_XXX in sky2.h)
	Control                      0x1800

Stuck is
	GMAC 1
	Status			     0x5810 (or 0x5A10)

First, here's the described hang in action, on the Core2 Duo on a 1Gb
hub:
GMAC 1 Status/Control remains at 0x5010/0x1800 until module is removed.
Read/write buffer pointers are changing.  Full ethtool output in
http://www.robsims.com/sky2.netmon.log.gz

This machine was also having major throughput problems - 17 kB/s.
Rebooting brought it to ~ 20 MB/s.  Booting into a kernel with the
proprietary sk98lin kernel module showed ~ 80MB/s.  Finally, returning
to sky2 gave 117 MB/s.  Tests run using netcat, dd, /dev/zero, and
/dev/null, transmitting from the problem box to an e1000 via a Netgear
GS108.  No hangs were observed during the "load test."

I also had a hang on a Pentium 4 w/sky2, 100Mb/s hub.  I neglected to
try removing and re-inserting the module before rebooting.
GMAC 1
Status                       0xF004
Control                      0x1800

RAMbuffer pointers not moving, Read buffer Read pointer != Write pointer.

Thanks for looking at this.

The vendor driver does not do hardware flow control correctly. It ignores
Tx pause frames.

Were you using Jumbo MTU?

This is [100mbit] [Full duplex] [Tx flow control disabled] [link up] 
	[Rx flow control disabled]

> Control                      0x1800

You might have over run the hub and it wedged.  Try doing:
	ethtool -r eth0
that forces a down/up

No - 1500.

I'm still seeing throughput drop to under 1 Mb/s (50-100kB/s)
periodically.  I did an ethtool -S and ethtool -d to capture state.
(sky2-fail.log).  I ran ethtool -r and retested; no change
(sky2-ethtool-r.log).  Finally, ifdown - rmmod - modprobe - ifup, which
restored to Gigabit speeds (96+ MB/s), (sky2-modcycle.log).

Please let me know if there's anything else I can poke into.  As a
reminder, this is a 88E8053 r20.  Next time I see a degradation, I'll
try cycling the switch.

I continued to have problems with this interface.  I tried bringing up
the second interface on the motherboard; I added a cable to the same hub
as the first interface and configured an address on the same subnet.
I intended to see if I could use it as a redundant interface for when
the first hung.  I haven't been able to test that, because now I haven't
seen a hang or slowdown since I brought the second interface up.  

Could the idle interface have generated an interrupt which is never
cleared because the interface is down?  Or something similar?
