[dpdk-dev] [v2 05/15] bnxt: Add support to load bnxt PMD on a SR-IOV VF

[Ajit Khaparde]

Add support to the bnxt PMD to load on a PCI VF.
1) VF cannot change parameters like - speed, autoneg and pause
2) If the VF MAC address shows up as all 0's it has to be provisioned
by the PF in the hypervisor.
