From 3cea7763ddc23182e89afff493626c9bcb656542 Mon Sep 17 00:00:00 2001 From: Vladimir Oltean Date: Sun, 28 Apr 2019 21:45:51 +0300 Subject: [PATCH] net: dsa: Skip calling .port_vlan_filtering on no change Even if VLAN filtering is global, DSA will call this callback once per each port. Drivers should not have to compare the global state with the requested change. So let DSA do it. Signed-off-by: Vladimir Oltean Reviewed-by: Andrew Lunn Signed-off-by: David S.
