Detailed Description
       libnet macros and symbloc constants

Define Documentation
   #define for_each_context_in_cq(l)   for (l = libnet_cq_head(); libnet_cq_last(); l =
       libnet_cq_next())
       Provides an interface to iterate through the context queue of libnet contexts. Before
       calling this macro, be sure to set the queue using libnet_cq_head().

   #define IN6ADDR_ERROR_INIT
       Value:.nf { { { 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff,
       0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff,				  0xff, 0xff } }
       }
       IPv6 error code

   #define LIBNET_DONT_RESOLVE	 0
       Used for libnet's name resolution functions, specifies that no DNS lookups should be
       performed and the IP address should be kept in numeric form.

   #define LIBNET_ERRBUF_SIZE	0x100
       The libnet error buffer is 256 bytes long.

   #define LIBNET_MAX_PACKET   0xffff
       The biggest an IP packet can be -- 65,535 bytes.

   #define LIBNET_MAXOPTION_SIZE   0x28
       IP and TCP options can be up to 40 bytes long.

   #define LIBNET_OFF	1
       Used several places, to specify 'on' or 'one'

   #define LIBNET_ON   0
       Used several places, to specify 'on' or 'one'

   #define LIBNET_PR2	0
       Used for libnet_get_prand() to specify function disposition

   #define LIBNET_RESOLVE   1
       Used for libnet's name resolution functions, specifies that a DNS lookup can be performed
       if needed to resolve the IP address to a canonical form.
