Subject: [PATCH net-next 01/18] net: dsa: mv88e6xxx: add max VID to info
Some chips don't have a VLAN Table Unit, most of them do have a 4K
table, some others as the 88E6390 family has a 13th bit for the VID.
Add a new max_vid member to the info structure, used to check the
presence of a VTU as well as the value used to iterate from in VTU
GetNext operations.
This makes the MV88E6XXX_FLAG_VTU obsolete, thus remove it.
