If anyone has any objections, please let me know. ------------------ From: Mugunthan V N commit b56d6b3fca6d1214dbc9c5655f26e5d4ec04afc8 upstream. 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.
