RealTek 8169S (re) and NFS server not responding

I have a problem since I changed the NIC of my server to a
<RealTek 8169S Single-chip Gigabit Ethernet> driver re.

I encounter a lots of NFS server not responding from any clients as soon
as the load on the network increase.

I had to do an horrible hack: I added the following script
on the server crontab every 2 minutes:

/sbin/ifconfig re0 mtu 1490
/bin/sleep 15
/sbin/ifconfig re0 mtu 1500

The performances are poor because after between 1 or 2 minutes, the NFS
server is not responding but it is usable.

Any idea besides changing the NIC?
