Subject: [PATCH 3/9] xfrm: Allow to use the layer2 IPsec GSO codepath for software crypto.
Date: Fri, 22 Dec 2017 12:24:33 +0100 [thread overview]
Message-ID: <20171222112439.12476-4-steffen.klassert@secunet.com> (raw)
In-Reply-To: <20171222112439.12476-1-steffen.klassert@secunet.com>
We now have support for asynchronous crypto operations in the layer 2 TX
path. This was the missing part to allow the GSO codepath for software
crypto, so allow this codepath now.
