-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.
