Dear all,

I got this problem on ethernet interface from broadcom netextreme 5721 (network 1).
The other cards are working (3 Intel 82541 PI). (network 0, network 2, network 3)
If i go through a tunnel (Linux or Astaro on the other side same thing):
ping -c3 -s 1397 network 0
PING 10.0.0.1 (10.0.0.1) 1397(1425) bytes of data.
