Subject: [ 158/171 ] drivers: net: ethernet: davinci_emac: use netif_wake_queue() while restarting tx queue stable review patch.
If anyone has any objections, please let me know.


From: Mugunthan V N <[email protected]>

[ Upstream commit 7e51cde276ca820d526c6c21cf8147df595a36bf ]

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.
