Tun.ko please? (A5E)

As cubie a5e is a dual eth board perfect for networking use case,
could the support offer a kind help to compile a tun.ko file for us?
Without it no VPN application can be used!

Thank you!

I have tried building it myself, ( using a527_cubie_a5e_bullseye_beta_20250303_raw_disk image)
but I have no luck with the linux-modules-extra-5.15.147 and linux-headers-5.15.147

Should I first install Allwinner’s kernel header? like
sudo apt install linux-headers-sunxi http://ppa.linuxfactory.or.kr

This is a Hardkernel repository?

Just for example… not really

It’s because I saw Radxa support replied in an old thread suggest similar step (but on rockchip apparently no applicable to Allwinner) How to load a tun module - Operating system distributions / Debian/Ubuntu - Radxa Community
