Hi. I've been playing around with the LNet for UDP communication, and
cannot figure out how to send UDP traffic from a specific source port.
it always seems to use a random high port when I send UDP
communication.

Before, we get into a discussion on why would I need this, there are
many documented protocols that use either the same or designated
source port, such as BootP/DHCP (UDP 68 client to UDP 67 server).
Other protocols need a designated source port for security/firewall
concerns. I'm just trying to figure out how to specify a source port
for my datagram.

Thanks.
