Subject: [PATCH] net: dsa: b53: fix CPU port unicast ARL entries for BCM5325/65
On BCM5325 and BCM5365, unicast ARL entries use 8 as the value for the
CPU port, so we need to translate it to/from 5 as used for the CPU port
at most other places.
Fixes: c45655386e53 ("net: dsa: b53: add support for FDB operations on 5325/5365")
