Subject: drivers: net: ethernet: cpsw: use netif_wake_queue() while restarting tx queue
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.
