ChangeSet 1.2199.8.28, 2005/03/22 18:44:45-08:00, [EMAIL PROTECTED]
[BONDING]: Use NETIF_F_LLTX in bonding device
Lock contention on the bonding device's xmit_lock can
become a bottleneck when 3 or more gige links are aggregated.
And it looks like it's unnecessary too, so use the
NETIF_F_LLTX flag to avoid grabbing this lock.
