Subject: [PATCH v3 17/38] virtio_config: disallow native type fields
Date: Wed, 5 Aug 2020 09:44:02 -0400	[thread overview]
Message-ID: <20200805134226.1106164-18-mst@redhat.com> (raw)
In-Reply-To: <20200805134226.1106164-1-mst@redhat.com>

Transitional devices should all use __virtioXX types (and __leXX for
fields not present in legacy devices).
Modern ones should use __leXX.
_uXX type would be a bug.
Let's prevent that.
