ocelot_mact_write() can be used for directly modifying an FDB entry
situated at a given row and column, as opposed to the current
ocelot_mact_learn() which calculates the row and column indices
automatically (based on a 11-bit hash derived from the {DMAC, VID} key).
ocelot_mact_lookup() can be used to retrieve the row and column at which
an FDB entry with the given {DMAC, VID} key is found.
