Subject: [RFC net-next 03/22] net: virtio_net: initialize mb bit of xdp_buff to 0
Date: Thu, 23 Jul 2020 13:42:15 +0200 [thread overview]
Message-ID: <f7b4192b77bf24b43f4cb54098aabaedd5fc06cf.1595503780.git.lorenzo@kernel.org> (raw)
In-Reply-To: <cover.1595503780.git.lorenzo@kernel.org>
Initialize multi-buffer bit (mb) to 0 in xdp_buff data structure.
This is a preliminary patch to enable xdp multi-buffer support.
