I don't know anything at all about this subject, but I believe the wan
HDLC stuff is sync only.

Noting that the ppp driver does all the async framing internally. And
interleaved with ppp specific stuff, so probably not re-usable even if
exported. Ref ppp_async_encode() in drivers/net/ppp/ppp_async.c

I assume it would have used a shared implementation if there was one.
But I could be wrong...
