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.

Linus Torvalds1da177e2005-04-16 15:20:36 -070011 * 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/
Jeff Garzik6aa20a22006-09-13 13:24:59 -040021 * Paul Gortmaker (06/98):
Linus Torvalds1da177e2005-04-16 15:20:36 -070022 * - sort probes in a sane way, make sure all (safe) probes
23 * get run once & failed autoprobes don't autoprobe again.
