| 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 |
| 18 | details. |
| 19 | |
| 20 | To compile this driver as a module, choose M here: the |
| 21 | module will be called lapb. If unsure, say N. |
