Subject: Using net/wan/hdlc with serdev

Hello everyone. I have a serdev driver that communicates with a
coprocessor using HDLC [1]. I am currently using my own HDLC
implementation, but someone pointed out to me that I might be able to
use `drivers/net/wan/hdlc` instead.
However, I am not quite sure how I am supposed to use it. I think I am
supposed to `register_hdlc_protocol` in the serdev probe. The
`hdlc_proto->netif_rx` callback is called when data is available, and
`hdlc_proto->xmit` is called to send data? What is the format of
`skb-data` in rx?
It would be great if someone could point me to some drivers that use
Linux internal HDLC implementation.
