Message-Id: <1303289719-16913-1-git-send-email-gizero@gmail.com> Date: Wed, 20 Apr 2011 10:55:19 +0200 From: Andrea Galbusera <gizero@...il.com> To: Pantelis Antoniou <pantelis.antoniou@...il.com>, Vitaly Bordug <vbordug@...mvista.com> Cc: linuxppc-dev@...ts.ozlabs.org, netdev@...r.kernel.org, linux-kernel@...r.kernel.org, Andrea Galbusera <gizero@...il.com> Subject: [PATCH 1/1] 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. Tested on a MPC5121 based board.
