  2. * INET An implementation of the TCP/IP protocol suite for the LINUX

  4. * interface as the means of communication with the user level.
  5. *
  6. * Holds initial configuration information for devices.

  11. * Fred N. van Kempen, <waltje@uWalt.NL.Mugnet.ORG>
  12. * Donald J. Becker, <becker@scyld.com>
  13. *
  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.
