port_l2mc_set() writes a static L2 multicast entry for a reserved group 01:80:C2:00:00:<last> in a given VLAN with a given member portmask. Slow-protocol frames must reach the management CPU without being flooded to other ports, but the RMA "trap" action cannot deliver to the internal NIC on this hardware - its destination is an external CPU attached to a physical port. The working alternative is to keep the RMA action at "forward" and constrain the egress with a static entry: the forward lookup then hits the entry's member mask instead of the VLAN flood mask. Hardware-verified on a SWTGW218AS in both directions: a mask without the CPU bit stops delivery to the CPU, a CPU-only mask delivers with no port egress. Lookups are IVL, so callers add one entry per VID they care about; rewriting the same MAC+VID replaces the entry in place. Used by the BPDU containment in the next commit; the pending LACP branch adopts it for 01:80:C2:00:00:02 the same way.
