+Subject: [PATCH] sdk_dpaa: update the xmit timestamp to avoid watchdog
+ timeouts
+
+Update txq0's trans_start in order to prevent the netdev watchdog from
+triggering too quickly. Since we set the LLTX flag, the stack won't update
+the jiffies for other tx queues. Prevent the watchdog from checking the
+other tx queues by adding the NETIF_HW_ACCEL_MQ flag.
