From 33b72b8e0faf7a39faabece584fd6da61cd8f8df Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Wed, 15 Jul 2015 08:17:36 +0000 Subject: [PATCH] ar8216: adjust ATU flushing in case of link changes If a link goes down, don't flush the complete ARL table. Only flush the entries for the respective port. Don't touch ARL table if a link goes up.
