Subject: [RFC net-next 21/22] net: mlx5: initialize mb bit in xdp_buff to 0
Date: Thu, 23 Jul 2020 13:42:33 +0200 [thread overview]
Message-ID: <042ee812c11d32a437100cc00462dbad08f66e40.1595503780.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.
