Implement support for FDB and MDB management for the RTL8365MB series
switches.
The hardware supports IVL by keying the unicast forwarding database with
the {MAC, VID, EFID} tuple. The Extended Filtering ID (EFID) is 3 bits
wide, providing 8 unique filtering domains. This driver reserves EFID 0
for standalone ports, effectively limiting the hardware offload to a
maximum of 7 bridges. The multicast database uses a {MAC, VID} key, with
ports from different bridges sharing the same multicast group.
Introduce a mutex lock (l2_lock) to protect concurrent L2 table updates.
Add support for forwarding database operations, including unicast and
multicast entry handling as well as fast aging support.
Set DSA switch flags assisted_learning_on_cpu_port and fdb_isolation.
