Subject: [dpdk-stable] [PATCH] ethdev: fix setting of MAC address
Date: Thu, 14 Dec 2017 18:15:31 +0100 [thread overview]
Message-ID: <20171214171531.10506-1-olivier.matz@6wind.com> (raw)
From: Laurent Hardy <laurent.hardy@6wind.com>
When a new mac address is set, it is saved in dev->data->mac_addrs
before the ethdev handler is called.
First, it is inconsistent with the other ethdev functions
rte_eth_dev_mac_addr_remove() and rte_eth_dev_mac_addr_add().
Moreover, it prevents the drivers from wrongly comparing the old address
and the new one, like it's done in i40evf driver:
if (is_same_ether_addr(mac_addr, dev->data->mac_addrs))
return;
Fixes: 943c2d899a0c ("net/i40e: set VF MAC from VF")
Fixes: 854d8ad4ef68 ("ethdev: add default mac address modifier")
