I'd like to put to the networking list that we take a serious look
at making the ALTQ code from Kenjiro Cho a standard part of FreeBSD.
I'm looking at adding some queueing methods into Netgraph
as part of some work being discussed by
phk, Archie, Brian and myself, Looking into this I note that
for the to be really effective we really want to have an
overall queueing strategy for the OS. We have at the moment,
the simplistic IFQ_ macro's, but I think that they have lived
long enough and done their duty.
I'd like to replace them (or at least supplement them)
in a way that allows us to have more comprehensive queue
support. If done correctly, (e.g the correct macro's
are added,) I think we can keep the performance degradation
to a minimum.
MY main reason right NOW is that in some cases, Netgraph
interfaces to exisiting code using the exisiting queues, and
if I want to add such things as queue priorities, I can't
do this unless the exisiting code also upgrades.
(e.g. the netgraph ethernet hooks deliver packets into the
same queue that the normal interface methods do.)
