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