*sonic/natsemi/ns83829: Move the National Semi-conductor drivers
Move the National Semi-conductor drivers into drivers/net/ethernet/natsemi/ and make the necessary Kconfig and Makefile changes. Also moved the 8390 (National Semi-conductor) devices as a sub-menu of National Semi-conductor devices. - moved the ibmlana driver as well into this directory since it is a "SONIC" driver CC: Alfred Arnold <alfred.arnold@lancom.de> CC: Thomas Bogendoerfer <tsbogend@alpha.franken.de> CC: Harald Welte <laforge@gnumonks.org> CC: Tim Hockin <thockin@hockin.org> CC: <linux-ns83820@kvack.org> CC: Kevin Chea <kchea@yahoo.com> CC: Marc Gauthier <marc@linux-xtensa.org> CC: Chris Zankel <chris@zankel.net> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com> Acked-by: Marc Gauthier <marc@tensilica.com>

- * (C) Waldorf Electronics, Germany
- * Written by Andreas Busse
- *
- * NOTE: most of the structure definitions here are endian dependent.
- * If you want to use this driver on big endian machines, the data
- * and pad structure members must be exchanged. Also, the structures
- * need to be changed accordingly to the bus size.
- *
- * 981229 MSch: did just that for the 68k Mac port (32 bit, big endian)
- *
- * 990611 David Huggins-Daines <dhd@debian.org>: This machine abstraction
- * does not cope with 16-bit bus sizes very well. Therefore I have
- * rewritten it with ugly macros and evil inlines.
- *
- * 050625 Finn Thain: introduced more 32-bit cards and dhd's support
- * for 16-bit cards (from the mac68k project).
