Do things improve if you turn off TSO in the atl1e driver?

ethtool -K eth0 tso off

Seems to work:

I get "operation not supported" when trying this ethtool command.
However, I compiled 2.6.28 with a patch to not set NETIF_F_TSO and
NETIF_F_TSO6 into netdev->features and I've been able to transfer
180 GB with scp overnight without running into any corrupted MACs.

One thing I do not understand - I thought the tso option was only
meaningful on the sender side ??? In my case, the transfers are going
from the external server to the local atl1e based interface...
