Subject: [PATCH v11 18/22] vfio: Define device_api strings
Date: Sat, 5 Nov 2016 02:40:52 +0530	[thread overview]
Message-ID: <1478293856-8191-19-git-send-email-kwankhede@nvidia.com> (raw)
In-Reply-To: <1478293856-8191-1-git-send-email-kwankhede@nvidia.com>

Defined device API strings. Vendor driver using mediated device
framework should use corresponding string for device_api attribute.
