From c3b8f85ec24674896aac9a6e41235b8d38db3dde Mon Sep 17 00:00:00 2001 From: Jacob Keller Date: Wed, 3 May 2017 10:28:59 -0700 Subject: igb: add statistic indicating number of skipped Tx timestamps The igb driver can only handle one Tx timestamp request at a time. This means it is possible for an application timestamp request to be ignored. There is no easy way for an administrator to determine if this occurred. Add a new statistic which tracks this, tx_hwtstamp_skipped.
