Re: [PATCH net-next v2] net: ti: icssg-prueth: Add HSR multicast FDB port membership management

In HSR offload mode, multicast addresses can be added via HSR master
(hsr0) or directly to slave ports (eth1/eth2). The FDB must track port
membership: P0 (0x1) for HSR master, P1 (0x2) for slave port 1, and P2
(0x4) for slave port 2. When the same address is added from multiple
paths, memberships must accumulate.

Implement a hybrid approach using __dev_mc_sync() callbacks to track
basic add/delete operations, checking netdev_hw_addr->synced to
distinguish HSR-synced addresses from direct additions. Post-process
to handle overlapping memberships by checking refcount:
- refcount=2 with synced=1: HSR only (P0)
- refcount>=3 with synced=1: HSR + direct (P0|P1/P2)
- synced=0 with P0 set: HSR removed, clean up orphaned P0

[...]
