description:
Linux does not implement SO_REUSEPORT, but allows reuse of a
host:port pair through SO_REUSEADDR even if the address is not a
multicast-address.  Effectively, this means that we should use
SO_REUSEPORT when SO_REUSEADDR is set (from the linux process)
to allow Linux applications to not exit with EADDRINUSE.
