From 987c658a61f432804c4662b736dbd5fc5939af1f Mon Sep 17 00:00:00 2001 From: Edward Cree Date: Fri, 27 Apr 2018 15:08:57 +0100 Subject: [PATCH] sfc: fix ARFS expiry check on EF10 Owing to a missing conditional, the result of rps_may_expire_flow() was being ignored and filters were being removed even if we'd decided not to expire them.
