Solution: Transmit timeouts

[Martin Siu]

It is so great because I also got the same problem. According to your
message posted in past, I have downloaded the latest driver of eepro100
for my linux-box RH6.0. However, I just get another problem when
recomplie the kernel.

Anyway, it is a good news for me.

Greetings,

After experiencing the infamous "Transmit timed out" messages from
eepro100.c on Intel 82559 boards, Donald suggested I try the version
1.09t
from ftp://cesdis.gsfc.nasa.gov/pub/linux/drivers/test/eepro100.c.  I am
pleased to report that this test driver version cured all problems that
I
had encountered.  In addition, I stress-tested this driver with a
"SmartBits" 100Mb throughput testing device.  With the new driver, the
test
completed without a single "Transmit timed out" message.  With previous
drivers, the test results were dismal (and peppered with tx timeouts).
Here are the results for the new driver, on a PIII 550 running 2.0.36
CONFIG_M686, optimize as router, forwarding UDP packets in router (two
card) mode with i82559 boards:
