bssgp_bvc_fsm: Set/get maximum BSSGP PDU length

Add functions to get/set the maximum supported BSSGP PDU size by the NS
layer.

IPv4 and IPv6 should not matter since we can just enable IP
fragmentation and send NS PDUs up to 2**16 + bytes. Frame relay does not
support fragmentation and this is the reason we need to be aware of the
maximum PDU size. Luckily with 1600 bytes the MTU in frame relay can hold a
regular IP packet including NS/BSSGP overhead.

On the NS layer this corresponds to the size of an NS SDU in NS-UNITDATA
(3GPP TS 48.016 Ch. 9.2.10)

libosmocore - set of Osmocom core libraries

This repository contains a set of C-language libraries that form the core infrastructure of many Osmocom Open Source Mobile Communications projects.

Historically, a lot of this code was developed as part of the OpenBSC project, but which are of a more generic nature and thus useful to (at least) other programs that we develop in the sphere of Free Software / Open Source mobile communications.

There is no clear scope of it. We simply move all shared code between the various Osmocom projects in this library to avoid code duplication.

The libosmocore.git repository build multiple libraries:

  • libosmocore contains some general-purpose functions like select-loop abstraction, message buffers, timers, linked lists
  • libosmovty contains routines related to the interactive command-line interface called VTY
  • libosmogsm contains definitions and helper code related to GSM protocols
  • libosmoctrl contains a shared implementation of the Osmocom control interface
  • libosmogb contains an implementation of the Gb interface with its NS/BSSGP protocols
  • libosmocodec contains an implementation of GSM voice codecs
  • libosmocoding contains an implementation of GSM channel coding
  • libosmosim contains infrastructure to interface SIM/UICC/USIM cards
