With this change, the timestamp variable is only used in ag71xx_check_dma_stuck. Small tx speedup. Based on a Qualcomm commit. ag->timestamp = jiffies was not replaced with netif_trans_update(dev) because of this quote: It should be noted that after this series several instances of netif_trans_update() are useless (if they occur in .ndo_start_xmit and driver doesn't set LLTX flag -- stack already did an update).
