>Description:
	
I would like to match packets by their size (for example to assign
small and big packets to different dummynet pipes), using len ranges
rather than or-blocks { iplen 1000 or iplen 1001 or ... }, like this:
	ipfw add pipe 10 ip from any to any iplen 1000-1500

Probably the same idea would be helpful with other options, like ipttl:
	ipfw add pipe 20 ip from any to any { ipttl 32-38 or ipttl 64-70 }
