Subject: [RFC net-next 22/22] net: mlx4: initialize mb bit in xdp_buff to 0
Date: Thu, 23 Jul 2020 13:42:34 +0200 [thread overview]
Message-ID: <58f38cdce05d1126f4a9372f0e14de7718af0a14.1595503780.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.
