From 210ca75d4949f1ace8ea53a75148806cc28224a0 Mon Sep 17 00:00:00 2001
From: "Russell King (Oracle)" <rmk+kernel@armlinux.org.uk>

Subject: [PATCH 4/5] net: mvneta: move tso_build_hdr() into
mvneta_tso_put_hdr()
Move tso_build_hdr() into mvneta_tso_put_hdr() so that all the TSO
header building code is in one place.
