RDS should do that right now, before the number is compiled into the code!

The registry is at http://www.iana.org/assignments/port-numbers

and the application form is http://www.iana.org/cgi-bin/usr-port-number.pl

It's supposed to be a two-week process, but it can take longer if you have
special requests like a specific port number, etc.

I don't think it has anything to do with the network stack code. It's basically
an Internet license plate, issued by a separate authority.
