Applied, but going forward please limit any refactoring and extensions
to the HDLC code. I thought you are actually using it. If that's not
the case let's leave the code be, it's likely going to be removed in
a few years time.

OK. I understand.

Thanks!

The HDLC layer is still used by X.25 people (to be precise, Martin
Schiller [off-list ref]). Although we currently have three X.25
drivers in the kernel (lapbether, x25_asy, hdlc_x25), it seems to me
that only hdlc_x25 is used in the real world. So I guess the HDLC
layer will be there as long as the X.25 stack is still there.
