From: Alejandro Lucero Date: Fri, 24 Aug 2018 14:25:36 +0000 (+0100) Subject: net/nfp: fix live MAC changes not supported X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=7712a1c660661005225c3f7ccbca09a6296e2751;p=dpdk.git net/nfp: fix live MAC changes not supported Some NFP firmwares support live changes to the MAC address, but this is not always true and the firmware advertises it accordingly. This patch checks if firmware does not support live changes and sets RTE_ETH_DEV_NOLIVE_MAC_ADDR in that case.
