Hmmm.... LAPB would expect to have an X.25 level 3 and maybe ISO
transport (class 0, 2 or 3) sat on top of it.

I actually used AF_PACKET sockets to transport data directly over LAPB
and it worked.

LAPB doesn't need anything from layer 3. It just sees the layer 3
packets as a sequence of packets, numbers them and reliably transports
them in order. It doesn't read the internal contents of the packets.
