From 2f614fe04f4463ff22234133319067d7361f54e5 Mon Sep 17 00:00:00 2001 From: Jeff Garzik Date: Thu, 5 Oct 2006 07:10:38 -0400 Subject: [PATCH] [netdrvr] b44: handle excessive multicast groups If there are more than B44_MCAST_TABLE_SIZE groups in the dev->mc_list, it will only listen to the first B44_MCAST_TABLE_SIZE that it sees. This change makes the driver go into RXCONFIG_ALLMULTI mode if there are more than B44_MCAST_TABLE_SIZE groups being subscribed to, similar to other network drivers.
