e1000, rx-checksumming and tx-checksumming problems

[Daniel Wagner]

Hi,

I'd like to report a bug with e1000 driver.  I have Intel PRO/1000 MT
nic which works fine as long 'rx-checksumming' and 'tx-checksumming'
is disabled.

newton:~# ethtool -k eth0
Offload parameters for eth0:
rx-checksumming: off
tx-checksumming: off
scatter-gather: on
tcp segmentation offload: on

If either rx or tx checksumming is enabled and I start copying large
file trees over NFS I see following in my logs:

thanks,

ps: I hope this is the right place to report a nic driver bug.
