backport commit b9e40857682ecfc5bcd0356a23ff409883ffb982
Author: David S. Miller <[EMAIL PROTECTED]>
Date: Tue Jul 15 00:15:08 2008 -0700
netdev: Do not use TX lock to protect address lists.
Now that we have a specific lock to protect the network
device unicast and multicast lists, remove extraneous
grabs of the TX lock in cases where the code only needs
address list protection.
