 * \brief
 * Basic Networking Types
 *
 * This module is responsible for defining the following basic networking
 * types:
 *
 *\li		struct in_addr
 *\li		struct in6_addr
 *\li		struct in6_pktinfo
 *\li		struct sockaddr
 *\li		struct sockaddr_in
 *\li		struct sockaddr_in6
 *\li		struct sockaddr_storage
 *\li		in_port_t
 *
 * It ensures that the AF_ and PF_ macros are defined.
 *
 * It declares ntoh[sl]() and hton[sl]().
 *
 * It declares inet_aton(), inet_ntop(), and inet_pton().
 *
 * It ensures that #INADDR_LOOPBACK, #INADDR_ANY, #IN6ADDR_ANY_INIT,
 * IN6ADDR_V4MAPPED_INIT, in6addr_any, and in6addr_loopback are available.
 *
 * It ensures that IN_MULTICAST() is available to check for multicast
 * addresses.
 *
 * MP:
 *\li	No impact.
 *
 * Reliability:
 *\li	No anticipated impact.
 *
 * Resources:
 *\li	N/A.
 *
 * Security:
 *\li	No anticipated impact.
 *
 * Standards:
 *\li	BSD Socket API
 *\li	RFC2553
