Subject: [PATCH v3 25/41] vhost/net: force len for TX to host endian
Date: Mon, 24 Nov 2014 13:54:24 +0200 [thread overview]
Message-ID: <1416829787-14252-26-git-send-email-mst@redhat.com> (raw)
In-Reply-To: <1416829787-14252-1-git-send-email-mst@redhat.com>
We use native endian-ness internally but never
expose it to guest.
