From f515f192ab4f45bb695146b82432d63d98775787 Mon Sep 17 00:00:00 2001 From: Vivien Didelot Date: Fri, 3 Feb 2017 13:20:20 -0500 Subject: net: dsa: add switch notifier Add a notifier block per DSA switch, registered against a notifier head in the switch fabric they belong to. This infrastructure will allow to propagate fabric-wide events such as port bridging, VLAN configuration, etc. If a DSA switch driver cares about cross-chip configuration, such events can be caught.
