ipfw: PRIO scheduler

[Muenz, Michael]

Hi,

On my FreeBSD system I always see :

load_dn_sched dn_sched PRIO loaded

I tried to gather some informations about this scheduler cause I never 
heard of,
but all I can find is an old thread about a kernel panic. Also no 
information via
man page, but I can successfully add a pipe with a PRIO scheduler.

Anyone here with some bits of knowledge what happened to this scheduler and
if it's for production use?

For me it sounds like a hard priority queue where everything else will 
starve
(when congested).

Thanks!
Michael
