I have here
|Ethernet controller: Intel Corporation 82567LM-2 Gigabit Network Connection
|0200: 8086:10cc

and I moved it to a bridge device. Since then I had problems mounting
NFS filesystem from machines which were using UDP for communication
(i.e. TCP works fine). After I disabled TX checksum offloading via
| ethtool --offload eth0 tx off
then the problem disappeared.

The same setup on 
|Ethernet controller: Intel Corporation 82541GI Gigabit Ethernet Controller 
(rev 05)
|0200: 8086:1076 (rev 05)

works without disabling offloading. Both machines run
2.6.34.7-56.fc13.x86_64. The working card uses e1000 while the "broken"
one runs with e1000e driver. Could this be a driver problem?
Unfortunately this is a productive machine so I can't take it down and
look into this myself.
