From 09c7570480f7544ffbf8e6db365208b0b0c154c6 Mon Sep 17 00:00:00 2001 From: Florian Westphal Date: Mon, 17 Jul 2017 13:57:26 +0200 Subject: xfrm: remove flow cache After rcu conversions performance degradation in forward tests isn't that noticeable anymore. See next patch for some numbers. A followup patcg could then also remove genid from the policies as we do not cache bundles anymore. Signed-off-by: Florian Westphal Signed-off-by: David S.
