NET: LAN91C96 CONFIG_NET_MULTIify
Make the lan91c96 driver capable of CONFIG_NET_MULTI to be clean for the new arch, add a a lil detect function Most of the formatting change was done to keep checkpatch silent, but a few functions and #if 0ed code which does not make sense for NET_MULTI have been removed Now, use the lan91c96_initialize() function to init the driver Signed-off-by: Nishanth Menon <nm@ti.com> Signed-off-by: Ben Warren <biggerbadderben@gmail.com>
