* Nov 3,  2000  Nenad Corbic    Added config_id to sdla_t structure.
*                               Used to determine the protocol running.
* Jul 13, 2000  Nenad Corbic	Added SyncPPP Support

* Oct 04, 1999  Nenad Corbic    New CHDLC and FRAME RELAY code, SMP support
* Jun 02, 1999  Gideon Hack	Added 'update_call_count' for Cisco HDLC 
*				support
* Jun 26, 1998	David Fong	Added 'ip_mode' in sdla_t.u.p for dynamic IP
*				routing mode configuration
* Jun 12, 1998	David Fong	Added Cisco HDLC union member in sdla_t
* Dec 08, 1997	Jaspreet Singh  Added 'authenticator' in union of 'sdla_t' 
* Nov 26, 1997	Jaspreet Singh	Added 'load_sharing' structure.  Also added 
*				'devs_struct','dev_to_devtint_next' to 'sdla_t'	
* Nov 24, 1997	Jaspreet Singh	Added 'irq_dis_if_send_count', 
*				'irq_dis_poll_count' to 'sdla_t'.
* Nov 06, 1997	Jaspreet Singh	Added a define called 'INTR_TEST_MODE'
* Oct 20, 1997	Jaspreet Singh	Added 'buff_intr_mode_unbusy' and 
*				'dlci_intr_mode_unbusy' to 'sdla_t'
* Oct 18, 1997	Jaspreet Singh	Added structure to maintain global driver
*				statistics.
* Jan 15, 1997	Gene Kozin	Version 3.1.0
*				 o added UDP management stuff
* Jan 02, 1997	Gene Kozin	Version 3.0.0
