From 33b203ff96584e26c7b2212950693484fbc452de Mon Sep 17 00:00:00 2001 From: Qi Zhang Date: Tue, 21 Feb 2017 17:45:29 -0500 Subject: [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 its startup/shutdown cycles. Now this is not necessary, since we already provide an API to set VF's MAC address from PF side (rte_pmd_i40e_set_vf_mac_addr). Application can use this API to lock down VF's mac address.(of course this should happen before VF init) While without this patch, we still can use rte_pmd_i40e_set_vf_mac_addr to overwrite the random one, but this patch align DPDK's default behavior with Kernel PF driver's, and this help to give an identical experience when work with kernel VF driver.
