From 1fdd512c92003cf2d671ba22753d13302bf8cd1d Mon Sep 17 00:00:00 2001 From: Tom Herbert Date: Thu, 4 Jun 2015 09:16:45 -0700 Subject: net: Add GRE keyid in flow_keys In flow dissector if a GRE header contains a keyid this is saved in the new keyid field of flow_keys. The GRE keyid is then represented in the flow hash function input. Signed-off-by: Tom Herbert Signed-off-by: David S.
