From 5e5d6fed374155ba1a7a5ca5f12fbec2285d06a2 Mon Sep 17 00:00:00 2001 From: Roopa Prabhu Date: Wed, 28 Feb 2018 22:43:22 -0500 Subject: ipv6: route: dissect flow in input path if fib rules need it Dissect flow in fwd path if fib rules require it. Controlled by a flag to avoid penatly for the common case. Flag is set when fib rules with sport, dport and proto match that require flow dissect are installed. Also passes the dissected hash keys to the multipath hash function when applicable to avoid dissecting the flow again. icmp packets will continue to use inner header for hash calculations.
