Subject: [PATCH] net: dsa: Sync static FDB entries on foreign interfaces to
 | 
						|
 hardware
 | 
						|
 | 
						|
Reuse the "assisted_learning_on_cpu_port" functionality to always add
 | 
						|
entries for user-configured entries on foreign interfaces, even if
 | 
						|
assisted_learning_on_cpu_port is not enabled. E.g. in this situation:
 | 
						|
 | 
						|
   br0
 | 
						|
   / \
 | 
						|
swp0 dummy0
 | 
						|
 | 
						|
$ bridge fdb add 02:00:de:ad:00:01 dev dummy0 vlan 1 master
 | 
						|
 | 
						|
Results in DSA adding an entry in the hardware FDB, pointing this
 | 
						|
address towards the CPU port.
 | 
						|
 | 
						|
The same is true for entries added to the bridge itself, e.g:
 | 
						|
 | 
						|
$ bridge fdb add 02:00:de:ad:00:01 dev br0 vlan 1 self
 |
