ESFQ (or SFQ updates) mainline status?

ESFQ (or SFQ updates) mainline status?

[Jeff Gustafson]

Hi all,
	I have a question about the status of the spiffy updates to SFQ.  I
*really* like the ESFQ idea.  I appears to be exactly what I'm looking
for.  From what I can tell from this mailing list, SFQ is getting some
or all of the ESFQ features.  Although the ESFQ web site gives detailed
information about the status for inclusion in mainline, I am having
trouble finding out exactly what (if any) parts of ESFQ got into SFQ in
mainline.
	Did any of the ESFQ-like enhancements for SFQ reach .23 or do I still
need to patch?  I am running a stripped-down Fedora 8 box and it would
be very convenient if the patches were already in .23 or added by the
Fedora team.
	I tried to run the ESFQ command against SFQ, but the command was
rejected:

/sbin/tc qdisc add dev eth1 parent 1:12 handle 12: sfq perturb 10 hash
ctnatchg

	It appears the even if the kernel does have the patches, the shipped
version tc does not.

				..Jeff

The mainline kernel doesn't have ESFQ, so the distribute version of iproute2
does not. If your distro chooses to add ESFQ to their kernel, then they
need to extend tc as well.
