Jocke,

I'll let you know if I find any.  For a starting point, I have an QE ATM
driver, that is more than likely similar in design <though no Ethernet
interface>, as it supports the QE engine, and just turns the UCC into =
ATM
mode, as opposed to HDLC mode. Would imagine the buffering, IO, =
interrupts
are similar. I am still in process of porting it up from the 82xx CPU.=20

Although HDLC how it registers itself into the kernel is a mystery to =
me, I
am having trouble finding any HDLC drivers to model this after.  Know of =
any
specs? API? Etc...
