From c674df973ad8af2074c834788e167332d81309fa Mon Sep 17 00:00:00 2001 From: Leon Romanovsky Date: Tue, 8 Mar 2022 20:36:15 +0200 Subject: net/mlx5: Store IPsec ESN update work in XFRM state mlx5 IPsec code updated ESN through workqueue with allocation calls in the data path, which can be saved easily if the work is created during XFRM state initialization routine. The locking used later in the work didn't protect from anything because change of HW context is possible during XFRM state add or delete only, which can cancel work and make sure that it is not running.
