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:

As said: Other NICs than the Atheros work fine.

If you need additional Infos (tcpdumps, etc.) please let me know.

Regards,
Martin
