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.
