Userspace applications can call kernel code via system calls. If u want 
to provide some new functionality to
userspace applications, you will need to declare the functions that you 
have written(bind, connect, recieve...)  as system calls, and compile 
the same into the kernel

   moreover, why do u need to implement a new protocol in this way? 
 cant you define a hook for the new protocol (unique protocol number) 
and use the existing socket calls?
