| 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. |
