From 01728e17eedc397953e0ad55f92e34bc78e23a70 Mon Sep 17 00:00:00 2001 From: Vivien Didelot Date: Tue, 23 Jun 2015 10:26:04 -0400 Subject: [PATCH] net: switchdev: ignore unsupported bridge flags switchdev_port_bridge_getlink() queries SWITCHDEV_ATTR_PORT_BRIDGE_FLAGS attributes, but a driver doesn't need to implement this in order to get bridge link information. So error out only on errors different than -EOPNOTSUPP. (This is a follow-up patch for 35ff109.)
