Chelsio 40Gbps NIC not detected

[digitalis99]

I'm trying to install N4F 10.2 on a box with a Chelsio T580-LP-CR adapter in it. It's compatible with FreeBSD 10.2, according to their site, and it uses the cxgbe(4) driver. After installation, when I go to configure the NIC's, no adapter shows in the list. Auto-detect does nothing. Ahh...not sure what to do next. Any pointers?

see the man page

To load the driver as a module at boot time, place the following lines in
loader.conf(5):

t4fw_cfg_load="YES"
t5fw_cfg_load="YES"
if_cxgbe_load="YES"

Thanks. I added those lines to /boot/loader.conf, as well as an additional line for a dual port 10Gbps Intel NIC in the same system. I rebooted the system, but still no network interfaces at all show up. Is there a good way to debug this to find out if the driver module is loaded at boot?

[digitalis99]

I answered a bit of my own question. I enabled some 1Gbps adapters on the system just so I could work in the GUI. I added those three lines to loader.conf via the GUI as well, just for kicks. I rebooted the machine and looked at the system log. It claimed the first two drivers were already loaded (t4fw and t5fw), I assume because there were definitions in loader.conf and loader.conf.local. There was no mention of cxgbe, though. I'm assuming that means the driver can't find suitable hardware?

If so, that would be a bummer, because I expressly bought that card so I could get it to work in N4F.

What mother board do you use?

if_cxgbe is builtin driver in NAS4Free 10.2 series.
If you can not see the device, first check with pciconf -lv.
If you have another PCIe slots, try to change the slot and remove all other cards.

Note that non-server grade mother board might have trouble due to BIOS.

[digitalis99]

The system is a Dell R720xd with 7 PCIe slots, so it should be capable. I can move the card around as a test. I'll grab the pciconf info as well.

Thanks for the pointers about pciconf. I ran that, and didn't see the adapter listed anywhere in the output. I moved the card to another slot, and POOF, it showed up on the next boot. Whodathunkit?
