Without this patch we have to manually bring up the CPU interface in
failsafe mode.
This was backported from kernel 5.12.

Subject: [PATCH] net: dsa: be louder when a non-legacy FDB operation fails
|
|
|
|
The dev_close() call was added in commit c9eb3e0f8701 ("net: dsa: Add
|
|
support for learning FDB through notification") "to indicate inconsistent
|
|
situation" when we could not delete an FDB entry from the port.
|
|
|
|
bridge fdb del d8:58:d7:00:ca:6d dev swp0 self master
|
|
|
|
It is a bit drastic and at the same time not helpful if the above fails
|
|
to only print with netdev_dbg log level, but on the other hand to bring
|
|
the interface down.
|
|
|
|
So increase the verbosity of the error message, and drop dev_close().
