[dpdk-dev] DPDK bnx2x driver link problem

[Saurabh Mishra]

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.
