From 5ea4d4688dcea7add275ae2e3654878a1834465d Mon Sep 17 00:00:00 2001 From: Bruce Richardson Date: Tue, 20 Jun 2017 16:23:10 +0100 Subject: [PATCH] net/ixgbe: remove fallback code for x86 non-SSE4 Since SSE4 is now part of minimum requirements for DPDK on x86, we no longer need this fallback code.
