This implements TCP ULP for SMC, helps applications to replace TCP with
SMC protocol in place. And we use it to implement transparent
replacement.

This replaces original TCP sockets with SMC, reuse TCP as clcsock when
calling setsockopt with TCP_ULP option, and without any overhead.

This looks very interesting. Can you provide a simple userspace example about 
how to use ULP with smc?

Here is a userspace C/S application:

Thanks for the example, it was very helpful!
