Subject: [PATCH v3 06/16] libqos: add missing virtio-9p feature negotiation
Date: Sat, 19 Oct 2019 07:38:00 +0100	[thread overview]
Message-ID: <20191019063810.6944-7-stefanha@redhat.com> (raw)
In-Reply-To: <20191019063810.6944-1-stefanha@redhat.com>

VIRTIO Device Initialization requires feature negotiation.  The libqos
virtio-9p driver lacks feature negotiation and is therefore
non-compliant.
