Description

cxgbe drivers support ALTq. cxl interface labels should supoort it:
https://www.freebsd.org/cgi/man.cgi?query=altq&apropos=0&sektion=0&manpath=FreeBSD+8.3-RELEASE&arch=default&format=html

https://github.com/pfsense/pfsense/blob/master/src/etc/inc/interfaces.inc#L5649
Needs "cxl" interface added to allow traffic shaping on the Chelsio interfaces.

I'll arbitrarily set this to high priority as it's hardware sold and bundled by NetGate, and the basic altq functionality is not available.

This problem is present in github and 2.3.2-RELEASE

History

#1 Updated by Jim Pingle 7 months ago

  • Category set to Traffic Shaper
  • Target version changed from 2.3.2_1 to 2.4.0

Can't target 2.3.2_1 as it's already been built.

There was a deliberate reason this was left out but I'll have to dig up the details tomorrow. Most likely reason was that it made no sense to allow. The performance hit you'd take for doing ALTQ on a 10G interface would never be worth it. You wouldn't gain much if anything from shaping at those speeds.

Well, ISP is limiting our network connectivity to 2GBps. With notes on 10gbps cards, I would assume that trying to traffic shape that quantity of traffic would be a bottleneck on the nic cards and/or cpu.

TL;DR:
I'm trying to traffic shape less than 3gbps on a 10gbps card.
