Checking the RTIME_UDP_ENABLE_IPALIASES disables filtering out IP aliases. Note that this currently only works on platforms where each IP alias has its own interface name, such as eth0:1, eth1:2 etc.

Checking the RTIME_UDP_ENABLE_TRANSFORMS_DOC enables UDP Transformations in UDP transport.

Checking the RTIME_UDP_EXCLUDE_BUILTIN removes UDP transport from being built.
