cne: Add reference count for Smart Wireless Interface Manager

Browse Source 
Add the reference count for Smart Wireless Interface Manager to
know whether there are any process who still has the socket in
question in use or not.
Enable INET DIAG.
Redefine the TCP_FLAG as it gives compiling error when an enum is defined
by a function return.
