Weird behaviour with an Intel i350-T4 Controller pfSense 2.2
-
Power management on the PCI express port is disabled, however could a buggy bios still cause the power management to screw around with the card or could the issue stem down from using MSIX interrupts?
-
Hard to say. The fact that it initially had a bad nvram doesn't inspire confidence.
Check the sysctl error counters for anything that looks odd compared to the working interface. I forget exactly where they are off-hand, I usually just grep for them on the few occasions I had to look, I think you'll see them with:sysctl dev.igbYou can narrow that down.

Grepping through sysctl didn't reveal any transmission errors or strange behavior.
Disabling flow-control is a complete no-go and forcing the kernel to use MSI interrupts made the controller unstable.
I did however raise the num_queues from 1 to 2.
Hardware TSO and LRO is disabled through the checkboxes in the WebGUI.However, until now as of writing, the connection between the pfsense box and the switch has been kept at 1000base-T full-duplex auto-negotiated for 6 hours now.
I'll keep investigating the issue..

You mean as opposed to MSI-X or regular interrupts? I would expect it to operate without MSI-X OK.
Is this a real i350-T4 or one of those coming directly from China at huge discount?
Spontaneously re-negotiating a new connection speed without being disconnected is something happening at a low level.

Yes, I reverted back to MSI-X interrupts. Must admit I haven't tried regular interrupts yet.
Before buying the controller I did read about the Chinese knockoffs here at the forum, so I ended up buying the card from Germany through ebay. (this listing actually: http://www.ebay.com/itm/111442450246?_trksid=p2060778.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT) as I shaved off 50% of the price compared to those in Denmark.
Indeed, I know the negotiation is happening in the NICs firmware at the physical layer :)

Hmm, I don't see 'Intel' on the PCB at all in that Ebay listing. Is it on the board you have? Also the Ethernet PHY ICs look wrong. Not looking good to be honest. :-\

Nope, no Intel logo, only the sticker on the back as shown in the listing.
I'll guess it's a Chinese knockoff then? :/

That would be my guess. Not that that's necessarily a problem, as you've probably read there are quite a few positive reviews here on the forum. However in light of the link issues I think I would be returning that ASAP.

Kinda suggested there:
Herstellungsland und -region (Country of origin): China
-
Aren't the real cards also built in China?
-
Steve, guess you're right, it's better RMA the product.
Looking through other listings I've noticed that proper NICs has the intel logo silkscreened on the pcb near the ethernet connectors.Doktornotor: I did notice that before ordering. The genuine cards are build in China too.

A little bit to late, but it solved the problem well out for me and other here in the pfsense forum
If you get your new Intel i350-T4, and this will be an original, please do a firmware update to the
latest version, and all will be running fine. Perhaps also for others how find this thread over Google
and owns the same problem. -
I confirm that a firmware upgrade resolve the problem. Thank you.
