[dpdk-dev] [PATCH] net/i40e: no more initial VF MAC address

During PF initialization, PF will generate an initial mac
address for VFs, the purpose is to help VF keep a constant
mac address between startup/shutdown cycles. Now this is not
necessary, since we already provide an API to set VF mac
address from PF side (rte_pmd_i40e_set_vf_addr). Application
can use this API to lock down VF's mac address.
This change also sync DPDK PF's behavior with kernel driver.
