From e2a85aecebc03d165bc2dcd233deadd5dd97ea9f Mon Sep 17 00:00:00 2001 From: Andrea Galbusera Date: Thu, 21 Apr 2011 02:21:21 +0000 Subject: powerpc: Fix multicast problem in fs_enet driver mac-fec.c was setting individual UDP address registers instead of multicast group address registers when joining a multicast group. This prevented from correctly receiving UDP multicast packets. According to datasheet, replaced hash_table_high and hash_table_low with grp_hash_table_high and grp_hash_table_low respectively. Also renamed hash_table_* with grp_hash_table_* in struct fec declaration for 8xx: these registers are used only for multicast there. Tested on a MPC5121 based board. Build tested also against mpc866_ads_defconfig. Signed-off-by: Andrea Galbusera Signed-off-by: David S.
