Here are my untested (but simple) changes to SFQ to make it "fair" on a per
ip basis.  I believe that this is actually what most people want - equal
bandwidth among a number of users without being tricked by users using many
connections.


In net/sched/sch_sfq.c:

                h = iph->daddr;
                h2 = iph->saddr^iph->protocol;
                if (!(iph->frag_off&htons(IP_MF|IP_OFFSET)) &&
                    (iph->protocol = IPPROTO_TCP ||
                     iph->protocol = IPPROTO_UDP ||
                     iph->protocol = IPPROTO_ESP))
                        h2 ^= *(((u32*)iph) + iph->ihl);
                break;

change to:

h = iph->daddr;
                h2 = iph->saddr^iph->protocol;
                if (!(iph->frag_off&htons(IP_MF|IP_OFFSET)) &&
                    (iph->protocol = IPPROTO_TCP ||
                     iph->protocol = IPPROTO_UDP ||
                     iph->protocol = IPPROTO_ESP))
                        h2 ^= *(((u32*)iph) + iph->ihl);
                break;
