All in-tree boards that use this controller have CONFIG_NET_MULTI added Also: - changed CONFIG_DRIVER_SMC91111 to CONFIG_SMC91111 - cleaned up line lengths - modified all boards that override weak function in this driver - modified all eeprom standalone apps to work with new driver - updated blackfin standalone EEPROM app after testing Signed-off-by: Ben Warren <biggerbadderben@gmail.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
