From c9e2105e295ebd123f9cded311f3e5678218f3f4 Mon Sep 17 00:00:00 2001 From: Arkadi Sharshevsky Date: Sun, 6 Aug 2017 16:15:44 +0300 Subject: [PATCH] net: dsa: Add support for querying supported bridge flags The DSA drivers do not support bridge flags offload. Yet, this attribute should be added in order for the bridge to fail when one tries set a flag on the port, as explained in commit dc0ecabd6231 ("net: switchdev: Add support for querying supported bridge flags by hardware").
