Hello

I wonder if anyone can suggest why previously working dpdk code may fail in
the Mellanox pmd code in dpdk-2.1.0, seemingly due to failure to create a
"resource domain" via ibv_exp_create_res_domain(). I must admit I haven't
seen that verb before, and it appears to be returning null with no error
message.

The DPDK log gives these hints:

PMD: librte_pmd_mlx4: 0xa4fc20: TX queues number update: 0 -> 1
PMD: librte_pmd_mlx4: 0xa4fc20: RX queues number update: 0 -> 1
PMD: librte_pmd_mlx4: 0xa4fc20: RD creation failure: Cannot allocate memory

I'm using dpdk-2.10.0 and  MLNX_OFED_LINUX-3.1-1.0.3 on ubuntu14.04 with a
connectx-3 card.

thanks
bill
