Hi!
The Linux compatibility layer, aka Linuxolator, is for running userland
Linux binaries on FreeBSD. I think what you're looking for is the Linux
KPI, or lkpi. I believe Mellanox network card drivers are using this, and I
know the drm-kmod graphics drivers are. This might be a starting point for
you.
Hi,
I was just wondering if I could find more documentation about
linuxolator. I have been reading up "FreeBSD Device Drivers" and I
think it will help me in understanding network drivers, but I couldn't
find much information on the linux kernel api other than a blog on
drm-kmod (setup).

THe linuxolator, as I told you, is for running userland Linux binaries
on FreeBSD, and has nothing to do with wanting to build Linux-only
network drivers.
I suggest you look at the code for the lkpi, you can find it here:
https://github.com/freebsd/freebsd/tree/master/sys/compat/linuxkpi/common
There are also drivers in the tree using it, such as mellanox network
drivers, I think.
The lkpi is meant to work like on Linux, but you probably need some glue
to set up modules and so on.
I suggest you start with looking at the relevant code.
