From 8663c938ceb72f47941c95ff0ea491ebbdd68f26 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Fri, 6 May 2011 16:32:47 -0700 Subject: sctp: Store a flowi in transports to provide persistent keying. Several future simplifications are possible now because of this. For example, the sctp_addr unions can simply refer directly to the flowi information. Signed-off-by: David S.
