net: dsa: add tagging driver for MaxLinear GSW1xx switch family
Add support for a new DSA tagging protocol driver for the MaxLinear
GSW1xx switch family. The GSW1xx switches use a proprietary 8-byte
special tag inserted between the source MAC address and the EtherType
field to indicate the source and destination ports for frames
traversing the CPU port.
Implement the tag handling logic to insert the special tag on transmit
and parse it on receive.
