Subject: [patch net-next v4 12/21] bridge: add new brport flag LEARNING_SYNC

From: Scott Feldman <sfeldma@...il.com>

This policy flag controls syncing of learned FDB entries to bridge's FDB.  If
on, FDB entries learned on bridge port device will be synced.  If off, device
may still learn new FDB entries but they will not be synced with bridge's FDB.
