From 8f4fbb9bfc8f0eac8932d45f57e29507d5b631a3 Mon Sep 17 00:00:00 2001 From: Alexander Duyck Date: Tue, 30 Oct 2012 06:01:40 +0000 Subject: [PATCH] ixgbe: Make TSO check for CHECKSUM_PARTIAL to avoid skb_is_gso check This change is meant to reduce the overhead for workloads that are not using either TSO or checksum offloads. Most of the time the compiler should jump ahead after failing this check to the VLAN check since in the ixgbe_tx_csum call we start with that check as well.
