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