Subject: B44: increase wait loop

The b44 Enet control disable bit may take longer to clear on some
systems, so the loop count is increased with this patch. Functionality
is not compromised, but a debug message can be seen when the bit is not
cleared within the count value.
Thanks to Vasileios Lourdas who reported the problem.

Subject: 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.

From d626f62b11e00c16e81e4308ab93d3f13551812a Mon Sep 17 00:00:00 2001
From: Arnaldo Carvalho de Melo <acme@redhat.com>
Date: Tue, 27 Mar 2007 18:55:52 -0300
Subject: [SK_BUFF]: Introduce skb_copy_from_linear_data{_offset}

To clearly state the intent of copying from linear sk_buffs, _offset being a
overly long variant but interesting for the sake of saving some bytes.
