    In my experience the Linux kernel interface to its drivers is quite
    unstable and driver code requires tweaks to work with the updated
    kernel.  There is a tight coupling between drivers and the kernel so
    that they have to be compiled with the kernel, or re-compiled based on
    specific kernel headers.  The driver interfaces are not mostly stable
    like they are with Solaris/Illumos.

    The reason why Linux works with so many devices is due to the many
    interested parties who work to keep it working.

    If someone was to compile the driver from source code they could use
    it with the Illumos kernel on their own system without violating GPL.
    Any small error might result in the OS needing to be re-installed
    and/or total loss of data.
