From 59b1a94c9a034e63a5e030a5154be1d4d84677d9 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Fri, 11 Mar 2011 19:23:02 -0500 Subject: net: Add flowiX_to_flowi() shorthands. This is just a shorthand which will help in passing around AF specific flow structures as generic ones. Signed-off-by: David S.
