ixg(4) and Intel X540?

[Hauke Fath <hf%spg.tu-darmstadt.de@localhost>]

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
