From 182ff8dfdb63e66ca81e4d3a4c746f8d578e5687 Mon Sep 17 00:00:00 2001 From: Alexander Duyck Date: Mon, 27 Apr 2009 22:35:33 +0000 Subject: [PATCH] igb/ixgbe: remove unecessary checks for CHECKSUM_UNNECESSARY Both of these drivers do a check to verify ip_summed is set to CHECKSUM_UNNECESSARY prior to passing the packet to GRO. GRO itself already does such a check so it is redundant and can be removed as this will likely cause out of order issues when receiving a packet that didn't pass checksum validation.
