It can be set on a per-(sub)interface basis. Instead of leaving it
default, and receiving 32 for PPPoEoE / 33 for PPPoEoVLAN / 34 for
PPPoEoQinQ, set NAS-Port-Type to 20001 for bba-group AAAA ports and
20002 for bba-group BBBB ports.

Pull them from your NMS based on interface description, and do bitwise
comparison on NAS-Port instead of string comparison on NAS-Port-Id.
