   2  * INET         An implementation of the TCP/IP protocol suite for the LINUX
   3  *              operating system.  INET is implemented using the  BSD Socket
   4  *              interface as the means of communication with the user level.
   5  *
   6  *              Holds initial configuration information for devices.

  14  * Changelog:
  15  *              Stephen Hemminger (09/2003)
  16  *              - get rid of pre-linked dev list, dynamic device allocation
  17  *              Paul Gortmaker (03/2002)
  18  *              - struct init cleanup, enable multiple ISA autoprobes.
  19  *              Arnaldo Carvalho de Melo <acme@conectiva.com.br> - 09/1999
  20  *              - fix sbni: s/device/net_device/
  21  *              Paul Gortmaker (06/98):
  22  *               - sort probes in a sane way, make sure all (safe) probes
  23  *                 get run once & failed autoprobes don't autoprobe again.
