LAN7800 script fails, interface runs at 100Mb/s

[monokinetic]

Attempting to follow the Seeed wiki page here on a recent install of Raspberry Pi os:
Linux raspberrypi 6.1.21-v7l+ #1642 SMP Mon Apr 3 17:22:30 BST 2023 armv7l

fails for me like this:

To Reproduce
Steps to reproduce the behavior:

1. Install latest Raspberry Pi OS from the rpi-installer on the supplied CM4
2. Follow the wiki page as linked and try the Ethernet section where the LAN7800 interface needs drivers to reach full speed.
3. Also note to even get this far the config.txt file required:
   arm64=0
4. Install the kernel headers.
5. See the dirs and command issued above as taken from Seeed wiki page.
6. The module fails to compile.

Expected behavior
To be able to run the LAN7800 interface at 1Gb/s as advertised.

Additional context
I'm attempting to debug my LAN7800 based port using OpenWRT, see issue42. See also forum thread here where I'm trying to get this hardware to work in any operating system. So far it always fails.

I am also having the same issue here. The script fails with the same make error.
