*
* Warning! The protocol described in this file is experimental and
* backward incompatible changes may be made. Backward compatible changes
* may be added together with the corresponding interface version bump.
* Backward incompatible changes are done by bumping the version number in
* the protocol and interface names and resetting the interface version.
* Once the protocol is to be declared stable, the 'z' prefix and the
* version number in the protocol and interface names are removed and the
* interface version number is reset.
