9	  Link Access Procedure, Balanced (LAPB) is the data link layer (i.e.
10	  the lower) part of the X.25 protocol. It offers a reliable
11	  connection service to exchange data frames with one other host, and
12	  it is used to transport higher level protocols (mostly X.25 Packet
13	  Layer, the higher part of X.25, but others are possible as well).
14	  Usually, LAPB is used with specialized X.21 network cards, but Linux
15	  currently supports LAPB only over Ethernet connections. If you want
16	  to use LAPB connections over Ethernet, say Y here and to "LAPB over
17	  Ethernet driver" below. Read
18	  <file:Documentation/networking/lapb-module.rst> for technical
19	  details.

21	  To compile this driver as a module, choose M here: the
22	  module will be called lapb.  If unsure, say N.
