unsigned int CoreDX_UdpTransportConfig::debug_flags

adjust the debug output from the transport

unsigned char CoreDX_UdpTransportConfig::do_meta_broadcast

enable broadcast of META (DPD discovery) data default: 0 (off)

unsigned char CoreDX_UdpTransportConfig::dynamic_interfaces

detect and handle changes to interface addresses

CoreDX_IpTransportInterfaceSeq CoreDX_UdpTransportConfig::interfaces
