Subject: [PATCH 1/5] xen/sndif: Introduce protocol version
Date:   Thu, 12 Apr 2018 19:00:58 +0300
Message-Id: <20180412160102.15833-2-oleksandr_andrushchenko@epam.com>
In-Reply-To: <20180412160102.15833-1-oleksandr_andrushchenko@epam.com>
References: <20180412160102.15833-1-oleksandr_andrushchenko@epam.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Protocol version was referenced in the protocol description,
but missed its definition. Fix this by adding a constant
for current protocol version.
