[linux_can] Would it be possible to add CAN FD support to linux_can ?

Hi,

first of all, great work on your repositories, I have checked out and played with the linux_can and it looks very good, I plan to use that together with the flutter-pi. Thanks for all that great work.

I am noob programmer, so can't do it myself really, unless there is someone willing to provide some guidance.
