So after some more looking around in the code, I think the
workflow is quite a bit different than what I thought in the
previous mail. I think I am supposed to allocate hdlc device using
`alloc_hdlcdev` in the `serdev->probe` and then implementing
`hdlc->xmit` to send data over UART. But well, I am not sure how to create an HDLC frame? Is there a
helper that creates HDLC frame skbuff for me? Or maybe the hdlc
implementation is simply not designed to be used for Asynchronous
framing [1]. It would be great if someone could explain how to use
this HDLC module or point to some resource I might have missed.
