be2net: Fix offload features for Q-in-Q packets
At least some of the be2net cards do not seem to be capabled of performing checksum offload computions on Q-in-Q packets. In these case, the recevied checksum on the remote is invalid and TCP syn packets are dropped. This patch adds a call to check disbled acceleration features on Q-in-Q tagged traffic.
