+ Revision 0.21: Uses the new generic socket option code.
+
+ Revision 0.22: Gcc clean ups and drop out device registration. Use the

+ Revision 0.23: IPX /proc by Mark Evans. Adding a route will
+ will overwrite any existing route to the same network.
+
+ Revision 0.24: Supports new /proc with no 4K limit
+
+ Revision 0.25: Add ephemeral sockets, passive local network

+ Revision 0.28: Small fix for multiple local networks <Thomas Winder>
+
+ Revision 0.29: Assorted major errors removed <Mark Evans>
+ Small correction to promisc mode error fix <Alan Cox>
+ Asynchronous I/O support. Changed to use notifiers

+
+ Revision 0.30: Moved to net/ipx/... <Alan Cox>
+ Don't set address length on recvfrom that errors.
+ Incorrect verify_area.
+
+ Revision 0.31: New sk_buffs. This still needs a lot of
+ testing. <Alan Cox>
+
+ Revision 0.32: Using sock_alloc_send_skb, firewall hooks. <Alan Cox>
+ Supports sendmsg/recvmsg
+
+ Revision 0.33: Internal network support, routing changes, uses a

+
+ Revision 0.34: Module support. <Jim Freeman>
+
+ Revision 0.35: Checksum support. <Neil Turton>, hooked in by <Alan Cox>
+ Handles WIN95 discovery packets <Volker Lendecke>
+
+ Revision 0.36: Internal bump up for 2.1
+
+ Revision 0.37: Began adding POSIXisms.
+
+ Revision 0.38: Asynchronous socket stuff made current.

+
+ Revision 042: Multithreading - use spinlocks and refcounting to

+ of ipx interfaces, etc.
+ Bugfixes - do refcounting on net_devices, check function
+ results, etc. Thanks to davem and freitag for

+
+ Revision 044: Call ipxitf_hold on NETDEV_UP - acme
+
+ Revision 045: fix PPROP routing bug - acme
+
+ Revision 046: Further fixes to PPROP, ipxitf_create_internal was
+ doing an unneeded MOD_INC_USE_COUNT, implement
+ sysctl for ipx_pprop_broacasting, fix the ipx sysctl
+ handling, making it dynamic, some cleanups, thanks to
+ Petr Vandrovec for review and good suggestions. (acme)
+
+ Revision 047: Cleanups, CodingStyle changes, move the ncp connection
+ hack out of line - acme
+
+ Revision 048: Use sk->protinfo to store the pointer to IPX private

+
+ Revision 049: SPX support dropped, see comment in ipx_create - acme
+
+ Revision 050: Use seq_file for proc stuff, moving it to ipx_proc.c - acme
+
+Other fixes:
+
+ Protect the module by a MOD_INC_USE_COUNT/MOD_DEC_USE_COUNT pair. Also, now
+ usage count is managed this way:
+ -Count one if the auto_interface mode is on
+ -Count one per configured interface
