From 01a545cf21e7514f0b384328e6387e637a07e333 Mon Sep 17 00:00:00 2001 From: Emil Tantilov Date: Thu, 27 Feb 2014 20:32:45 -0800 Subject: ixgbevf: add check for CHECKSUM_PARTIAL when doing TSO This patch adds check for CHECKSUM_PARTIAL to avoid the skb_is_gso check in ixgbevf_tso(). It should reduce overhead for workloads that are not using TSO or checksum offloads. It is the same as in ixgbe.
