  Modified files:
    .                    packet-ip.c 
  Log:
  Clean up the checksumming stuff a bit:
  
  	have "ip_checksum()" compute the checksum of the IP header;
  
  	have "ip_checksum_state()" call "ip_checksum()" and then return
  	TRUE if the result is 0 and FALSE otherwise;
  
  	have "ip_checksum_shouldbe()" save the current value of the
  	checksum field in the header, set that field to 0, call
  	"ip_checksum()" to get the checksum, restore the value of the
  	checksum field in the header to the saved value, and then return
  	what "ip_checksum()" returned;
  
  rather than having duplicated code to compute checksums.
