One of the modems we may use comes up over USB and presents itself to the host as a network interface.  the documentation says that the linux host needs vlan (8021q kernel module).
Has this ever been used on VOXL1?
If not, is there any reason it couldn't be installed?
Thanks,
Ed

It's safe to say we have not tried it.

You can build the kernel using the instructions here: https://gitlab.com/voxl-public/system-image-build/voxl-build

Thanks Chad...
I'll dig into this; meanwhile, someone here suggested that perhaps we can fork the kernel, then just build the module and install that with modprobe (without actually updating the on-board kernel). 
Has that kind of thing ever been done with VOXL1?
