SubjectRe: zilog 8530 SCC based cards
I don't know much about those sync hdlc lines, so I'm just guessing here (please
enlighten me):

* AX.25 uses HDLC. So the basic difference is just the encapsulation, right?
(Maybe the FCS is different, but it should be trivial to make that
configurable).

* Is it easy/difficult/impossible to have different encapsulations with the
same driver?

* Such sync hdlc lines do operate full duplex, don't they?

* The DMA SCC driver currently only does half duplex, although I'd like
to change that. The PackeTwin could do full duplex (using DMA channels 1
and 3), the PI2 _cannot_.
