Hello.
I am studying linux kernel 1.3.0.

In ip.c this sentence appeared.

if(iph->frag_off)
        {
                if (iph->frag_off & 0x0020)
                        is_frag|=1;
                /*
                 * Last fragment ?
                 */

                if (ntohs(iph->frag_off) & 0x1fff)
                        is_frag|=2;
        }

what is that mean is_frag?
what's the difference between is_frag are 1,2,4?

Thank you.
