Date: Sun, 01 Apr 2007 13:10:28 -0400 From: Bill Helfinstine <bhelf@...tterfly.whirpon.com> To: zambrano@...adcom.com, jgarzik@...ox.com Cc: netdev@...r.kernel.org, bhelf@...tterfly.whirpon.com Subject: [PATCH 2.6.21-rc5] b44: fix IFF_ALLMULTI handling of CAM slots If you set the IFF_ALLMULTI flag on a b44 device, or if you join more than B44_MCAST_TABLE_SIZE multicast groups, the device will stop receiving unicast messages. This is because the __b44_set_mac_addr call sets the zeroth CAM entry to the MAC address of the device, and then the loop at line 1722 proceeds to overwrite it unless the value of i is set by the __b44_load_mcast call. However, when IFF_ALLMULTI is set, that call is bypassed, leaving i set to zero. Fixed by starting the loop at 1 to make it skip the CAM entry for the MAC address.
