I am not yet sure about error: variable-sized object may not be initialized except with an empty initializer.
sys/endian.h does not exist on macOS, there are machine/endiah.h, if that is needed, otherwise the local endian.h perhaps can be used.
net/if_vlan_var.h does not exist at least on some macOS versions.
So while we can likely fix a lot of the header issues, my concern is that we won't work with the kernel at all.
For example on BSD we use route(4) and on Linux we use rtnetlink. Does one of these work on Darwin? If so then it might be possible. It took a long time and a lot of research to get Illumed supported and I don't have that time right now.
@rsmarples route(4) should work, and back to very old macOS versions. See: https://leopard-adc.pepas.com/documentation/Darwin/Reference/ManPages/man4/route.4.html
Generally speaking, a lot of BSD stuff will be supported (though not everything, admittedly). Less so for linuxisms, I think.
