3.8-stable review patch.  If anyone has any objections, please let me know.

------------------


From: Mugunthan V N <mugunthanvnm@xxxxxx>

[ Upstream commit b56d6b3fca6d1214dbc9c5655f26e5d4ec04afc8 ]

To restart tx queue use netif_wake_queue() intead of netif_start_queue()
so that net schedule will restart transmission immediately which will
increase network performance while doing huge data transfers.
