IPv4v6 comment

Prior to this commit, there was a global variable baseNetAddress that
could be set independently through a setter and also through the
configuration module. This baseNetAddress (16 bits IPv4) would then be
complemented with two more bytes in nas_config().

However, this is counter-productive, as not only we have a global
variable that is avoidable (we can give the entire address to
nas_config() directly), but it also would not work with IPv6. Hence,
modify to give nas_config() the entire address. A follow-up commit will
add IPv6 support.

-To compile:

-To get help
-
-   ./pt --help

-Some pregenerated messages (RRC and MAC) can be found in the PACKET_TRACER/messages directory.  Here are some
