Subject: [PATCH RFC v2 5/5] esp: Don't require synchronous crypto fallback on offloading anymore.
Date: Fri, 15 Dec 2017 10:13:08 +0100 [thread overview]
Message-ID: <20171215091308.23626-6-steffen.klassert@secunet.com> (raw)
In-Reply-To: <20171215091308.23626-1-steffen.klassert@secunet.com>
We support asynchronous crypto on layer 2 ESP now.
So no need to force synchronous crypto fallback on
offloading anymore.
