From 8ae5bcdc5d98a99e59f194101e7acd2e9d055758 Mon Sep 17 00:00:00 2001 From: Vivien Didelot Date: Fri, 19 May 2017 17:00:54 -0400 Subject: net: dsa: add MDB notifier Add two new DSA_NOTIFIER_MDB_ADD and DSA_NOTIFIER_MDB_DEL events to notify not only a single switch, but all switches of a the fabric when an MDB entry is added or removed. For the moment, keep the current behavior and ignore other switches. Signed-off-by: Vivien Didelot Reviewed-by: Florian Fainelli Signed-off-by: David S.
