[dpdk-dev] [PATCH v3 1/2] net/i40e: new API to add VF MAC address from PF

[Wenzhuo Lu <wenzhuo.lu@intel.com>]

Currently, rte_eth_dev_mac_addr_add is used by a
testpmd CLI to add a MAC address for VF. But the
parameter 'pool' of this API means the VMDq pool,
not VF.
So, it's wrong to use it to add the VF MAC address.
This patch provides a new API that can be used to
add VF MAC address on i40e.
