the actual tag format differs significantly, hence we need a dedicated
tag driver for that.

Reusing the same EtherType for two different DSA tagging protocols is
very bad news, possibly with implications also for libpcap. Is the
EtherType configurable in the MXL862xx family?

Only the egress EtherType can be configured, there is currently no way
to configure the ingress EtherType the switch expects to receive on
special-tag packets on the CPU port. MaxLinear, however, said they could
in theory release a new firmware changing the EtherType to any suggested
value, but it would be incompatible with existing downstream drivers in
the field, obviously.
