  14* ============================================================================
  15* Nov 3,  2000  Nenad Corbic    Added config_id to sdla_t structure.
  16*                               Used to determine the protocol running.
  17* Jul 13, 2000  Nenad Corbic    Added SyncPPP Support
  18* Feb 24, 2000  Nenad Corbic    Added support for x25api driver
  19* Oct 04, 1999  Nenad Corbic    New CHDLC and FRAME RELAY code, SMP support
  20* Jun 02, 1999  Gideon Hack     Added 'update_call_count' for Cisco HDLC 
  21*                               support
  22* Jun 26, 1998  David Fong      Added 'ip_mode' in sdla_t.u.p for dynamic IP
  23*                               routing mode configuration
  24* Jun 12, 1998  David Fong      Added Cisco HDLC union member in sdla_t
  25* Dec 08, 1997  Jaspreet Singh  Added 'authenticator' in union of 'sdla_t' 
  26* Nov 26, 1997  Jaspreet Singh  Added 'load_sharing' structure.  Also added 
  27*                               'devs_struct','dev_to_devtint_next' to 'sdla_t' 
  28* Nov 24, 1997  Jaspreet Singh  Added 'irq_dis_if_send_count', 
  29*                               'irq_dis_poll_count' to 'sdla_t'.
  30* Nov 06, 1997  Jaspreet Singh  Added a define called 'INTR_TEST_MODE'
  31* Oct 20, 1997  Jaspreet Singh  Added 'buff_intr_mode_unbusy' and 
  32*                               'dlci_intr_mode_unbusy' to 'sdla_t'
  33* Oct 18, 1997  Jaspreet Singh  Added structure to maintain global driver
  34*                               statistics.
  35* Jan 15, 1997  Gene Kozin      Version 3.1.0
  36*                                o added UDP management stuff
  37* Jan 02, 1997  Gene Kozin      Version 3.0.0
