From 2fd527b72bb6f95dfe8a1902e998cb76390c431e Mon Sep 17 00:00:00 2001 From: Petr Machata Date: Wed, 12 Dec 2018 17:02:48 +0000 Subject: net: ndo_bridge_setlink: Add extack Drivers may not be able to implement a VLAN addition or reconfiguration. In those cases it's desirable to explain to the user that it was rejected (and why). To that end, add extack argument to ndo_bridge_setlink. Adapt all users to that change. Following patches will use the new argument in the bridge driver. Signed-off-by: Petr Machata Acked-by: Jiri Pirko Reviewed-by: Ido Schimmel Signed-off-by: David S.
