LAPB doesn't check for write_queue length in lapb_data_request(). So
in some conditions it may grow unlimited. There is a potential problem
for small systems.

It seems like this for me:

It doesn't enforce limits on any of it's queued from what
I can tell.

Without a thorough audit of resource limit enforcement in
this protocol stack, changing things here might be more
trouble than it's worth.
