[PATCH net-next 02/20] net: dsa: change scope of notifier call chain

From: Vivien Didelot
Date: Fri May 19 2017 - 17:08:52 EST


Change the scope of the fabric notification helper from the DSA slave to
the DSA port, since this is a DSA layer specific notion, that can be
used by non-slave ports (CPU and DSA).
