*
* Demultiplex 802.2 encoded protocols. We match the entry by the
* SSAP/DSAP pair and then deliver to the registered datalink that
* matches. The control byte is ignored and handling of such items
* is up to the routine passed the frame.
*
* Unlike the 802.3 datalink we have a list of 802.2 entries as
* there are multiple protocols to demux. The list is currently
* short (3 or 4 entries at most). The current demux assumes this.
