bridge/fdb: add flag/indication for FDB entry synced from offload device
|
|
|

|
|
|
4aca6e |
Add NTF_EXT_LEARNED flag to neigh flags to indicate FDB entry learned by
|
|
|
4aca6e |
device has been learned externally to bridge FDB. For these entries,
|
|
|
4aca6e |
add "external" annotation in bridge fdb show output:
|
|
|
4aca6e |
|
|
|
4aca6e |
00:02:00:00:03:00 dev swp2 used 2/2 master br0 external
|
|
|
4aca6e |
00:02:00:00:03:00 dev swp2 self permanent
|
|
|
4aca6e |
|
|
|
4aca6e |
In the example above, 00:02:00:00:03:00 is shown twice on dev swp2. The
|
|
|
4aca6e |
first entry if from the bridge (master) and is marked as "external" by
|
|
|
4aca6e |
the offload device. The second entry is from the brport offload device (self),
|
|
|
4aca6e |
and was learned by the device.
