From 010c8f01aa7fe18ea97d302e1c7e9ca83bc27433 Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Wed, 20 Feb 2019 16:58:26 -0800 Subject: [PATCH] net: Get rid of switchdev_port_attr_get() With the bridge no longer calling switchdev_port_attr_get() to obtain the supported bridge port flags from a driver but instead trying to set the bridge port flags directly and relying on driver to reject unsupported configurations, we can effectively get rid of switchdev_port_attr_get() entirely since this was the only place where it was called.
