There is also another problem having to do with future extensibility of
METADATA_HW_PORT_MUX for DSA. I don't know how much of this is going to
be applicable for qca8k, but DSA tags might also carry such information
as trap reason (RX) or injection type (into forwarding plane or control
packet; the latter bypasses port STP state) and the FID to which the
packet should be classified by the hardware (TX). If we're going to
design a mechanism which only preallocates metadata dst's for ports,
it's going to be difficult to make that work for more information later on.
