 In your previous mail you wrote:

   Is the checksum into the IP header is nessesarily calculated or modules can 
   ommit it and save the overhead of recomputing it at meny nodes along the 
   route, especially when the IP is being serving a reliable transport protocol 
   such as TCP which contains a another checksum for important fields inside 
   the IP header itself?
   
=> the IPv4 header checksum is mandatory. If you believe it is not more
useful on modern networks, just use IPv6 which has no header checksum...
