Release 4.14 net/802/p8022.c

Directory: net/802
 *      NET3:   Support for 802.2 demultiplexing off Ethernet
 *              This program is free software; you can redistribute it and/or
 *              modify it under the terms of the GNU General Public License
 *              as published by the Free Software Foundation; either version
 *              2 of the License, or (at your option) any later version.
 *              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.
