For these entries, add "external" annotation in bridge fdb show output: 00:02:00:00:03:00 dev swp2 used 2/2 master br0 external 00:02:00:00:03:00 dev swp2 self permanent In the example above, 00:02:00:00:03:00 is shown twice on dev swp2. The first entry if from the bridge (master) and is marked as "external" by the offload device. The second entry is from the brport offload device (self), and was learned by the device.
