Subject: [PATCH net-next 4/7] net/sonic: Remove redundant netif_start_queue()
 call
Date:   Sun, 16 Feb 2020 08:03:32 +1100
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

The transmit queue must be running already otherwise sonic_send_packet()
would not have been called. If the queue was stopped by the interrupt
handler, the interrupt handler will restart it again.
