Hi Nitin,

This doesn't fix the problem for me. If I try to transfer, with scp, a
2gb file to DomU from Dom0, the transfer is disconnected with the
following error:

Received disconnect from 192.168.1.3: 2: Corrupted MAC on input.

Unlike dropping packets, there's actual corruption that domU is seeing
and ending the transfer. There's a buffer that's being overwritten. I
can reproduce this on an SMP system. 

Thanks,

Dan
