I personnaly use the following rules on egress of my external interface
to "prioritize" (although that's not Dummynet do) some packets.  This
works very well, I can make two parallel uploads at full upstream
bandwidth without my SSH session or my download being impacted :

ACKs:			tcp from any to any iplen 40-60 tcpflags ack
Interactive SSH:	tcp from any to any 22 iptos lowdelay
			tcp from any 22 to any iptos lowdelay
DNS requests:		udp from any to any 53
Small PONG:		icmp from any to any icmptype 8 iplen 1-200
HTTP(S), FTP:		tcp from any to any 21,80,443
