* 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
* Feb 24, 2000 Nenad Corbic Added support for x25api driver
* 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
