Subject: [PATCH 6/9] virtio: fix support for big-endian clients
Date: Sun, 28 Feb 2021 20:08:33 +0100 [thread overview]
Message-ID: <20210228190836.1451663-6-ahmad@a3f.at> (raw)
In-Reply-To: <20210228190836.1451663-1-ahmad@a3f.at>
With virtio 1.0 everything is little endian. Add back the Version 1.0
check that got lost during porting virtio to barebox.
