Subject: [PATCH RFC v2 4/5] xfrm: Allow IPsec GSO with software crypto for local sockets.
Date: Fri, 15 Dec 2017 10:13:07 +0100	[thread overview]
Message-ID: <20171215091308.23626-5-steffen.klassert@secunet.com> (raw)
In-Reply-To: <20171215091308.23626-1-steffen.klassert@secunet.com>

With support of async crypto operations in the GSO codepath
we have everything in place to allow GSO for local sockets.
This patch enables the GSO codepath.
