You should probably include the switch driver that is going to be
benefiting from doing these changes in the patch series, provide a cover
letter when sending more than one patch, and also combine both the add
and delete parts.

Since you already have visibility into proto, it may not be necessary at
all for now to define a BRIDGE_VLAN_INFO_8021AD bit in order to pass
that flag down to DSA for programming the VLAN, just pass proto to
dsa_port_vid_add() or a boolean flag which indicates whether this is the
customer or service tag that you are trying to program?
