bnx2x: Utilize FW 7.10.51
- (L2) In some multi-function configurations, inter-PF and inter-VF
Tx switching is incorrectly enabled.
- (L2) Wrong assert code in FLR final cleanup in case it is sent not
after FLR.
- (L2) Chip may stall in very rare cases under heavy traffic with FW GRO
enabled.
- (L2) VF malicious notification error fixes.
- (L2) Default gre tunnel to IPGRE which allows proper RSS for IPGRE packets,
L2GRE traffic will reach single queue.
- (FCoE) Fix data being placed in wrong buffer when corrupt FCoE frame is
received.
- (FCoE) Burst of FIP packets with destination MAC of ALL-FCF_MACs
causes FCoE traffic to stop.
