History
oleg 7eef73ab3f 1) dummynet_io() declaration has changed. 
2) Alter packet flow inside dummynet: allow certain packets to bypass
dummynet scheduler. Benefits are:

- lower latency: if packet flow does not exceed pipe bandwidth, packets
  will not be (up to tick) delayed (due to dummynet's scheduler granularity).
- lower overhead: if packet avoids dummynet scheduler it shouldn't reenter ip
  stack later. Such packets can be fastforwarded.
- recursion (which can lead to kernel stack exhaution) eliminated. This fix
  long existed panic, which can be triggered this way:
  	kldload dummynet
	sysctl net.inet.ip.fw.one_pass=0
	ipfw pipe 1 config bw 0
	for i in `jot 30`; do ipfw add 1 pipe 1 icmp from any to any; done
	ping -c 1 localhost

3) Three new sysctl nodes are added:
net.inet.ip.dummynet.io_pkt -		packets passed to dummynet
net.inet.ip.dummynet.io_pkt_fast - 	packets avoided dummynet scheduler
net.inet.ip.dummynet.io_pkt_drop -	packets dropped by dummynet

P.S. Above comments are true only for layer 3 packets. Layer 2 packet flow
     is not changed yet.
