It offers a reliable 11*6a2e9b73SSam Ravnborg connection service to exchange data frames with one other host, and 12*6a2e9b73SSam Ravnborg it is used to transport higher level protocols (mostly X.25 Packet 13*6a2e9b73SSam Ravnborg Layer, the higher part of X.25, but others are possible as well). 14*6a2e9b73SSam Ravnborg Usually, LAPB is used with specialized X.21 network cards, but Linux 15*6a2e9b73SSam Ravnborg currently supports LAPB only over Ethernet connections. If you want 16*6a2e9b73SSam Ravnborg to use LAPB connections over Ethernet, say Y here and to "LAPB over 17*6a2e9b73SSam Ravnborg Ethernet driver" below.

If unsure, say N. 23
