ixg(4) and Intel X540?

[Hauke Fath]

Hi,

I have a batch of servers here with an Intel X540-T1 10GbE card that I
had hoped would be recognized as ixg(4) by NetBSD, but no...

pci1 at ppb0 bus 1
vendor 0x8086 product 0x1528 (ethernet network, revision 0x01) at pci1
dev 0 function 0 not configured

OpenBSD 5.6 probes it as

ix0 at pci1 dev 0 function 0 "Intel X540T" rev. 0x01: msi, address
a0:36:9f:23:21:fc

but then fails to detect a carrier.

FreeBSD 10.1 probes it as

ix0: <Intel(R) PRO/10GbE PCI-Express Network Driver, Version - 2.5.15>
mem 0xf6000000-0xf61fffff,0xf6200000-0xf6203fff irq 16 at device 0.0 on
pci1
ix0: Using MSIX interrupts with 5 vectors
ix0: Ethernet address: a0:36:9f:23:21:fc
ix0: PCI Express Bus: Speed 5.0GT/s Width x8

and then fails to recognize the cd drive it just booted from, so I
couldn't run ifconfig.

I understand that the NetBSD ixg(4) was ported from FreeBSD
<http://comments.gmane.org/gmane.os.netbsd.devel.network/12284>. What
would it take to support the X540?

Cheerio,
hauke

I would suggest suggest sending the card to someone who volunteered to
look at the driver (like msaitoh) but doesn't have the hardware.

Or he could try to merge the diffs from FreeBSD, the code was similar
last time I checked.

Really? The FreeBSD driver for 1G Intel parts is much more like the
Linux driver and ours is this one-file thing that I couldn't decipher. I
never looked at the 10G driver because I was afraid it would be similar.

At a minimum there's some PHY code you're going to copy over (PHYs are
supposed to set themselves up with no help but that's really nonsense)
and some device IDs. Then comes the validation.

Well, if this hadn't been intimidating enough...

I tried porting openbsd's changes to msk(4) a while back (kern/49270),
and even got it into ifconfig(8), but never a packet on the wire. And
that's a far cry in complexity compared to the above. So I am kind of
discouraged.

Cheerio,

I don't think it is as bad as it looks :-)

No, that's BETTER. That means less delta between the FreeBSD and NetBSD
driver.

I would suggest suggest sending the card to someone who volunteered to
look at the driver (like msaitoh) but doesn't have the hardware.

That might be difficult; the NICs weren't cheap, and we're talking
about state property here.

I could set up a development machine or two with root access and serial
console, though.

For 1G, it's ok for me to buy by myself, but for 10G it's too expensive
as you said :)

Yes. dyoung@ ported the driver to make the delta small. It's not bad.
The problem is that no one have maintained the driver for your years...

I have no my own Intel 10G card. A few months ago, I borrowed an 82598(old!)
card.

Give me the accessibility.

Thanks for looking into this!

Unfortunately, I am currently home with the flu. I will get back to you
as soon as I am back to work.

Do you need any particular network / machine setup?

At least, please connect another machine which can reply to ICMP echo
on the same L2.
