From 335075989fbb3c3fffc3ba238b893fa92508a6f1 Mon Sep 17 00:00:00 2001 From: Jesse Brandeburg Date: Thu, 16 Apr 2015 20:06:11 -0400 Subject: [PATCH] i40e/i40evf: remove time_stamp member The driver doesn't use the time_stamp member to determine if there is a tx_hang any more. There really isn't any point to the variable at all so just remove it. It was left over from a previous tx_hang design.
