[ Upstream commit 5a59a58ec25d44f853c26bdbfda47d73b3067435 ]
LAN9303 doesn't associate FDB (ALR) entries with VLANs, it has just one global Address Logic Resolution table [1].
Ignore VID in port_fdb_{add|del} methods, go on with the global table. This is the same semantics as hellcreek or RZ/N1 implement.
Visible symptoms: LAN9303_MDIO 5b050000.ethernet-1:00: port 2 failed to delete 00:xx:xx:xx:xx:cf vid 1 from fdb: -2 LAN9303_MDIO 5b050000.ethernet-1:00: port 2 failed to add 00:xx:xx:xx:xx:cf vid 1 to fdb: -95
