I'm currently working on a driver that=20 provides point to point connection and I would like to use the sppp = driver=20 in order to get PPP stack over it.

I have few questions about the sppp=20 driver:

- As I understood from = the code,=20 the sppp driver prepends the ppp frame over the given data to = sppp_output and=20 than calls if_start (which should do the actual sending). The same goes=20 with control messages in the sppp_cp_send func. But, in the later = case, the=20 control messages are queued to the control queue

(sp->pp_cpq) which the = if_start=20 functions doesn't have access to. Should I implement the = access?

- How do you recommend connecting = my ioctrl=20 functions to the sppp ioctrl function (I have to call the ioctrl = function=20 because, as I understood it, this is the way to start the lcp = messaging). I=20 think the best way is to do this in the sppp_attach = function.

- Is there any resource = about using the=20 sppp driver. The sppp man page isn't satisfying at all.

Thank you,
