From ba162f8eed61a7e71e26455ce1cff5b5898a3579 Mon Sep 17 00:00:00 2001 From: Florian Westphal Date: Tue, 3 May 2016 16:31:00 +0200 Subject: [PATCH] netdevice: add helper to update trans_start trans_start exists twice: - as member of net_device (legacy) - as member of netdev_queue In order to get rid of the legacy case, add a helper for the dev->trans_update (this patch), then convert spots that do dev->trans_start = jiffies to use this helper (next patch). This would then allow us to change the helper so that it updates the trans_stamp of netdev queue 0 instead. Signed-off-by: Florian Westphal Signed-off-by: David S.
