I implement accessor for special equipment (acessing fiscal information)
which uses custom protocol over LAPB. As it is being implemented,
I actually wanted to know if this approach for using LAPB is good enough
for mainline submission, as I want to have kernel part to be in mainline.
I think I will have the rest of patches ready within two weeks.

All the best,
