Hi @all,
unfortunately I don't have the old postings any more, so I start a new
thread.
Following situation:
I have a Server (NFS) and a Client with the Atheros network card. If I
transfer big files, the md5sum of these files differ.
If I try to scp the file I get "MAC corrupted on inpu".
Everything works fine, if running on any other OS (or with other NICs
than the Atheros one).
So here is the data:

Is it only happening for IPv6 traffic, or is it also buggy for IPv4 ?
If you disable tso , does the bug disappear ?

It also happens with IPv4 (usually not so fast as with IPv6):
