[neutron-dynamic-routing] Support for multiple BGP speaker

Hi, As understood from the code, currently the neutron dynamic routing supports only one BGP speaker per host *# os-ken can only support One *speaker if* self.cache.get_hosted_bgp_speakers_count() == 1: raise bgp_driver_exc.BgpSpeakerMaxScheduled(count=1) * Could you please let me know if this is due to some limitation of the os-ken driver? Or are there any other reasons for this limitation? Thanks, Manu
