From fdd1a5303efb03bfa4016f29a519f0e553739069 Mon Sep 17 00:00:00 2001 From: Julian Wiedmann <jwi@linux.ibm.com> Date: Wed, 17 Apr 2019 18:17:30 +0200 Subject: [PATCH] s390/qeth: don't bother updating the last-tx time As the documentation for netif_trans_update() says, netdev_start_xmit() already updates the last-tx time after every good xmit. So don't duplicate that effort. One odd case is that qeth_flush_buffers() also gets called from our TX completion handler, to flush out any partially filled buffer when we switch the queue to non-packing mode. But as the TX completion handler will _always_ wake the txq, we don't have to worry about the TX watchdog there. Signed-off-by: Julian Wiedmann <jwi@linux.ibm.com> Signed-off-by: David S.
