*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>
