0009 Link Access Procedure, Balanced (LAPB) is the data link layer (i.e.
0010 the lower) part of the X.25 protocol. It offers a reliable
0011 connection service to exchange data frames with one other host, and
0012 it is used to transport higher level protocols (mostly X.25 Packet
0013 Layer, the higher part of X.25, but others are possible as well).
0014 Usually, LAPB is used with specialized X.21 network cards, but Linux
0015 currently supports LAPB only over Ethernet connections. If you want
0016 to use LAPB connections over Ethernet, say Y here and to "LAPB over
0017 Ethernet driver" below. Read
0018 <file:Documentation/networking/lapb-module.rst> for technical
0019 details.

0021 To compile this driver as a module, choose M here: the
0022 module will be called lapb. If unsure, say N.
