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.
|
