{nl,cfg,mac}80211: implement dot11MeshHWMPconfirmationInterval
As defined in section 13.10.9.3 Case D (802.11-2012), this control variable is used to limit the mesh STA to send only one PREQ to a root mesh STA within this interval of time (in TUs). The default value for this variable is set to 2000 TUs. However, for current implementation, the maximum configurable of dot11MeshHWMPconfirmationInterval is restricted by dot11MeshHWMPactivePathTimeout.
