From fdeea7be88b12742bfd50d9e19a06c0d2e702400 Mon Sep 17 00:00:00 2001 From: Ido Schimmel Date: Thu, 16 Mar 2017 09:08:15 +0100 Subject: [PATCH] net: vrf: Set slave's private flag before linking Allow listeners of the subsequent CHANGEUPPER notification to retrieve the VRF's table ID by calling l3mdev_fib_table() with the slave netdev. Without this change, the netdev won't be considered an L3 slave and the function would return 0. This is consistent with other master device such as bridge and bond that set the slave's private flag before linking. It also makes do_vrf_{add,del}_slave() symmetric.
