/* net_init.c: Initialization for network devices. */ /* Written 1993,1994,1995 by Donald Becker. The author may be reached as becker@scyld.com, or C/O Scyld Computing Corporation 410 Severn Ave., Suite 210 Annapolis MD 21403 This file contains the initialization for the "pl14+" style ethernet drivers. It should eventually replace most of drivers/net/Space.c. It's primary advantage is that it's able to allocate low-memory buffers. A secondary advantage is that the dangerous NE*000 netcards can reserve their I/O port region before the SCSI probes start. Modifications/additions by Bjorn Ekwall <bj0rn@blox.se>: ethdev_index[MAX_ETH_CARDS] register_netdev() / unregister_netdev() Modifications by Wolfgang Walter Use dev_close cleanly so we always shut things down tidily. Changed 29/10/95, Alan Cox to pass sockaddr's around for mac addresses. 14/06/96 - Paul Gortmaker: Add generic eth_change_mtu() function. 24/09/96 - Paul Norton: Add token-ring variants of the netdev functions. 08/11/99 - Alan Cox: Got fed up of the mess in this file and cleaned it up. We now share common code and have regularised name allocation setups. Abolished the 16 card limits. 03/19/2000 - jgarzik and Urban Widmark: init_etherdev 32-byte align 03/21/2001 - jgarzik: alloc_etherdev and friends */ #include <linux/config.h> #include <linux/module.h> #include <linux/errno.h> //#include <linux/kernel.h> #include <linux/sched.h> #include <linux/types.h> //#include <linux/fs.h> #include <linux/slab.h> #include <linux/if_ether.h> #include <linux/lib.h> #include <linux/netdevice.h> #include <linux/etherdevice.h> //#include <linux/fddidevice.h> //#include <linux/hippidevice.h> //#include <linux/trdevice.h> //#include <linux/fcdevice.h> //#include <linux/if_arp.h> //#include <linux/if_ltalk.h> //#include <linux/rtnetlink.h> //#include <net/neighbour.h> #define rtnl_lock() ((void)0) #define rtnl_unlock() ((void)0) /* The network devices currently exist only in the socket namespace, so these entries are unused.
