To use the amateur radio protocols within Linux you will need to get a
suitable copy of the AX.25 Utilities. More detailed information about these
and associated programs can be found on http://zone.pspt.fi/~jsn/.
For more information about the AX.25, NET/ROM and ROSE protocol stacks, see

The Packet Layer Protocol (PLP) is a way to route packets over X.25
connections in general and amateur radio AX.25 connections in
particular, essentially an alternative to NET/ROM.
A comprehensive listing of all the software for Linux amateur radio
users as well as information about how to configure an AX.25 port is
contained in the AX25-HOWTO, available from
