        "The version of Spanning Tree Protocol the bridge is
         currently running.  The value 'stpCompatible(0)'
         indicates the Spanning Tree Protocol specified in
         IEEE 802.1D-1998 and 'rstp(2)' indicates the Rapid
         Spanning Tree Protocol specified in IEEE 802.1w and
         clause 17 of 802.1D-2004.  The values are directly from
         the IEEE standard.  New values may be defined as future
         versions of the protocol become available.
