From 93a30947821c203d08865c4e17ea181c9668ce52 Mon Sep 17 00:00:00 2001 From: Sabrina Dubroca Date: Wed, 2 Nov 2022 22:33:13 +0100 Subject: macsec: delete new rxsc when offload fails Currently we get an inconsistent state: - netlink returns the error to userspace - the RXSC is installed but not offloaded Then the device could get confused when we try to add an RXSA, because the RXSC isn't supposed to exist.
