From 6b26b51b1d13c62a09f55d745b06a8e964900715 Mon Sep 17 00:00:00 2001 From: Arkadi Sharshevsky Date: Thu, 8 Jun 2017 08:44:14 +0200 Subject: net: bridge: Add support for notifying devices about FDB add/del Currently the bridge doesn't notify the underlying devices about new FDBs learned. The FDB sync is placed on the switchdev notifier chain because devices may potentially learn FDB that are not directly related to their ports, for example: 1. Mixed SW/HW bridge - FDBs that point to the ASICs external devices should be offloaded as CPU traps in order to perform forwarding in slow path. 2. EVPN - Externally learned FDBs for the vtep device. Notification is sent only about static FDB add/del. This is done due to fact that currently this is the only scenario supported by switch drivers.
