From: Jiri Pirko Date: Fri, 19 Feb 2010 08:48:47 +0000 (+0000) Subject: net/pcmcia: convert to use netdev_for_each_mc_addr X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=91fea5858418127ad33e0060f726c62be0047eaf;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git net/pcmcia: convert to use netdev_for_each_mc_addr removed fill_multicast_tbl function in smc91c92_cs and do the work inline rewritten set_addresses function in xirc2ps_cs. This was kinda headache. Simulated the original and new functions and they bahave the same. Signed-off-by: Jiri Pirko Signed-off-by: David S.
