Mellaox nic binding to driver.

[animesh tripathi]

Hi Team,

Do I need to bind the mellanox nic to any driver to use it with dpdk. In
case of intel, I am binding the pcie with igb_uio driver.

In case of mellanox nic, if I am binding the mellanox nic to igb_io, I am
getting the following error:

EAL: Detected 24 lcore(s)
EAL: Detected 1 NUMA nodes
EAL: Auto-detected process type: PRIMARY

Calling DPDK-Init for PDCP

But when I do not bind the mellanox nic to any driver, it is working fine.

Please let me know if my approach is correct.

Thanks,
