This is a new userspace operation, which will be done if the client-core version is greater than or equal to 2.9.6. This will provide a way to implement optional features and to determine which features are supported by the client-core. If the client-core version is older than 2.9.6, no optional features are supported and the op will not be done. The intent is to allow protocol extensions without relying on the client-core's current behavior of ignoring what it doesn't understand. Signed-off-by: Martin Brandenburg <martin@omnibond.com>
