Looks like bnx2x has link problem…sometime it sees link up and most of the
time it see link down even though the RX/TX counters are going up.
Has anybody seen this type of problem? If I don't use DPDK then I don't see
this type of link related problem.
The counter shows that it’s receiving and transmitting packets.
I tried with –n1, -n2 and –n4.
