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