From f053752fc64abedd834fbbc40fcab60b7c0a7e8f Mon Sep 17 00:00:00 2001 From: Jarno Rajahalme Date: Mon, 28 Apr 2014 17:31:26 -0700 Subject: [PATCH] openvswitch.h: Clarify use of key attributes. Key attributes relating to actual packet headers are ignored for OVS_PACKET_CMD_EXECUTE as the header key attributes are retrieved from the packet itself.
