[U-Boot] [PATCH 1/3] NET: LAN91C96 CONFIG_NET_MULTIify
Nishanth Menon
nm at ti.com
Fri Oct 16 07:06:35 CEST 2009
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
