Traffic shaping with Chelsio T520-SO-CR

[jharper]

I've setup pfsense 2.3.2 on a Dell PowerEdge R220 with a Chelsio T520-SO-CR 10Gb nic configured with the following interfaces:

WAN (wan)      -> cxl1      -> v4: xxx.xxx.xxx.xxx/28
VLAN1 (lan)    -> cxl0_vlan1 -> v4: 192.168.1.1/24
VLAN5 (opt1)    -> cxl0_vlan5 -> v4: 192.168.5.1/24
VLAN10 (opt2)  -> cxl0_vlan10 -> v4: 192.168.10.1/24
VLAN14 (opt3)  -> cxl0_vlan14 -> v4: 192.168.14.1/24

All working fine except that the Traffic Shaping wizard can't seem to see the WAN interface: the dropdown only lists the vlan interfaces. I'm aware that the nic driver must be compatible with ALTQ for shaping to work and as I understand it, this nic is using the cxgbe driver which is listed as supported on the ALTQ manpage, but I don't know how to verify for certain that this is the driver actually being used.

How can I troubleshoot what is causing this issue, whether it's driver related or something else?

Many thanks,
Joe.

Is there anyone else with this nic able to use traffic shaping?

Have you tried manually creating the ALTQ queues?
