      Description

      When running onos with the Mininet

      Custom Topology ( topo-perf-2sw.py ) :

              s1 = self.addSwitch( "s1", dpid="0000000000000001" )

        h1 = self.addHost( "h1" )
        self.addLink( s1, h1 )
      sudo mn --custom ~/mininet/custom/topo-perf-2sw.py --topo mytopo --mac --controller remote --switch ovsk,protocols=OpenFlow13

       Then, assign switches to controller :

      sh ovs-vsctl set-controller s1 tcp:10.192.19.111:6653

      Once in 5-20 times frequency, it fails to assign controller since it fails to find the device with switch's dpid.

       

      Starting seeing this issue after the patchset :

      https://gerrit.onosproject.org/#/c/17487/

      From the new function:

      private boolean isGroupCapable(OpenFlowSwitch sw) {
Driver driver = driverService.getDriver(DeviceId.deviceId(Dpid.uri(sw.getDpid())));
if (driver == null) {
return true;
}
String isGroupCapable = driver.getProperty(GROUP_CAPABLE);
return isGroupCapable == null || Boolean.parseBoolean(isGroupCapable);
}

      When it tries to get driver, it fails to find the device:

      failing point : 
driverService.getDriver(DeviceId.deviceId(Dpid.uri(sw.getDpid())));

      and throws an exception:
