[Click] tx timeout fix

[Jason Park]

Hi Srivas

What e1000 device are you using?
If your device support PACKET_SPLIT and you turned on, you should turn off
it.
Make sure un-define CONFIG_E1000_PACKET_SPLIT on 6.1.16.62.DB driver.
It works well for me with disable packet split and replacing skb_clone to
skb_copy.

Hello Adam and Beyers,

I've been lately testing the timeout fixes you had posted on a
click-patched 2.6.16.13 kernel. The results therefrom still seem to show
stability problems. Though the timeouts don't occur predictably or as
often as before, I still encounter them and kernel panics randomly, and
with a higher probability when testing with high loads. Notably, I see
these problems well pronounced with bidirectional (full-duplex)
operation of the driver, both with FromDevice and PollDevice. I've
tested the 5.x driver patch as well as the 6.1.16.62.DB version patch,
and seen similar results.

Please do let me know of the details of a stable 2.6.x configuration
that you were able to set up using these patches. Further, any idea if
and when the fixes will eventually get in to the main source tree of the
e1000 driver on sourceforge?

Thanks a bunch in advance,
Srivas.
