X722 drivers for Linux Kernel 2.6.x

[VS77]

I have a need for X722 drivers for an older linux kernel.  Attempting to build a rpm from the e1000e-3.8.7 tarball (claims to work all the way back to linux 2.4) results in errors for missing include files that don't seem to be on 2.6

Setup:  Legacy software running RHEL5.2 on an upgraded motherboard with onboard X722 ethernet ports.  The kernel version cannot be changed, but hardware drivers can be added or updated.

Kindly confirm the driver version currently using for X722 Intel® Ethernet Controllers.

The ports show up in "lspci", but not in "ip a" or "ifconfig"

a "find" in /sys/bus/pci/drivers/ for the pci addresses returns nothing.

I found that the e1000e driver does exist in the kernel, and loaded it.

after

echo 8086 37d2 > /sys/bus/pci/drivers/e1000e/new_id

and

echo 0000:00:08.0 > /sys/bus/pci/drivers/e1000e/bind

I get 

bash: echo: write error: Input/output error

Does the x722 only work with i40e?

I'm currently looking into backporting i40e, but there's not much support left for Linux 2.6.18-419 and backporting is new to me.

Hello VS77,

Greetings for the day!

Have you already tried the latest driver from our site below?

Intel® Network Adapter Driver for PCIe* 40 Gigabit Ethernet Network Connections under Linux*

https://www.intel.com/content/www/us/en/download/18026/intel-network-adapter-driver-for-pcie-40-gigabit-ethernet-network-connections-under-linux.html

 We'd like to inform you that that RHEL5.2 is not listed as validated Operating System on X722. You may consider testing the driver on supported OS.

Supported Operating Systems for Intel® Ethernet Controllers (LOM)

Unfortunately I do not get to choose the Operating System.

i40e won't build that easily because it needs 2.6.32 or later while I'm on 2.6.18
