From 4eea37d7b92076fdeac2a21e5f4dbd92d286719d Mon Sep 17 00:00:00 2001 From: Or Gerlitz Date: Sun, 18 Sep 2016 18:20:28 +0300 Subject: net/mlx5: E-Switch, Fix error flow in the SRIOV e-switch init code When enablement of the SRIOV e-switch in certain mode (switchdev or legacy) fails, we must set the mode to none. Otherwise, we'll run into double free based crashes when further attempting to deal with the e-switch (such as when disabling sriov or unloading the driver).
