From 9c2f186e45faa34d5f6ff52aa84c361d4be72288 Mon Sep 17 00:00:00 2001 From: Alexander Duyck Date: Wed, 6 Jan 2016 23:11:26 -0800 Subject: [PATCH] igb: Drop unnecessary checks in transmit path This patch drops several checks that we dropped from ixgbe some ago. It should not be possible for us to be called with either of the conditional statements returning true so we can just drop them from the hot-path.
