Need help

[Igor V. Ruzanov]

Hello, FreeBSD colleagues!
Trying to forward my question to freebsd-net@ group, meybe there is a 
chance to dig the answer

I have modern network card Intel i350T2V2 (peripheral dual gigabit port NIC). 
And as far as i know all Intel cards should be normally detected by the system. 
But with this NIC i have some troubles:
- the system sees the card as some ethernet device but cannot find proper (igb) 
driver:
pcib6: <ACPI PCI-PCI bridge> irq 47 at device 3.2 on pci0
pci6: <ACPI PCI bus> on pcib6
pci6: <network, ethernet> at device 0.0 (no driver attached)
pci6: <network, ethernet> at device 0.1 (no driver attached)
- its from dmesg log.

My server is:
- system is FreeBSD-10.3-RELEASE-p20
- motherboard: Intel S2600WT (dual CPU socket board)
- one CPU installed

Maybe someone has experience with this inetl NIC? As seen from pciconf output 
the NIC has a set of VFs (Virtual Functions) needed in virtualization 
environments. And chip id is 0x151F8086 - the id that igb-driver does not know 
about. Maybe i need some preconfiguration of this card? Or this device is not 
compatible with non-virtualization systems like usual physical server?

Big thanks in advance!
