From cfc77c2fbadf5b806fea2e35738c7437fc62f522 Mon Sep 17 00:00:00 2001 From: Shradha Shah Date: Wed, 20 May 2015 11:09:30 +0100 Subject: sfc: save old MAC address in case sriov_mac_address_changed fails Otherwise the PF and VF can disagree on the VF's MAC address and this leads to strange behaviour, up to and including kernel panics.
