SR-IOV is supported using bnx2x poll mode driver running as VF driver and
native linux driver running as PF (in host/hypervisor). There is no issue
while running with the PF driver which is at the base version as that of
PMD. However, there is a compatibility issue between newer out-of-box PF
drivers with older VF driver. So the newer VFs would also need to send
BNX2X_VF_TLV_PHYS_PORT_ID (among other TLVs) to differentiate between
newer and older VFs.

Thanks,
Harish
