Oops, I was wrong, it stopped to receive any packets.

I did netperf test over Mellanox 23108 4X HCA against r2720, after a while the HCA stopped to accept packets.
I am pretty sure it's a bug in driver not IPoIB. rmmod ib_ipoib didn't help, after removing ib_mthca, and restarted, the driver worked again. It's easy to reprocude on my 4-way intel based systems.
I did saw the below messages from /var/log/messages, when this happened.
Jun 29 12:13:53 elm3a238 kernel: ib_mthca 0000:04:00.0: Port change to down for port 1
Jun 29 12:13:55 elm3a238 kernel: ib_mthca 0000:04:00.0: Port change to active for port 1
And the HCA didn't accept ARP reply packet afterwards.
Now I am adding a permanent arp entry to avoid this problem. It seems to work fine. Anybody else saw this problem?
