Subject: [PATCH net-next v2 2/2] rocker: Explicitly mark learned FDB entries as offloaded

Currently, FDB entries that are notified to the bridge driver via
'SWITCHDEV_FDB_ADD_TO_BRIDGE' are always marked as offloaded by the
bridge. With MAB enabled, this will no longer be universally true.
Device drivers will report locked FDB entries to the bridge to let it
know that the corresponding hosts required authorization, but it does
not mean that these entries are necessarily programmed in the underlying
hardware.

We would like to solve it by having the bridge driver determine the
offload indication based of the 'offloaded' bit in the FDB notification
[1].

Prepare for that change by having rocker explicitly mark learned FDB
entries as offloaded. This is consistent with all the other switchdev
drivers.
