In the IP-SNS SGSN role, we need to inform the BSS of our local
IP endpoints. For statically configured NSEs, those are explicitly
stated on a per-NSE level.
For dynamically created IP-SNS NSEs, we are adding a new VTY
command, using which the administrator can configure which binds
should be advertised as IP endpoints to such BSS.

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

this is a bit of a hack. Q.933 explicitly forbids either side from ever
sending a sequence number of '0'. Values start from '1' and are modulo 256,
but '0' is always skipped. So if the peer is sending us a "last received
sequence number of '0' it means it has not yet received any packets from us,
which in turn can only mean that it has just been restarted. Let's treat
this as "service affecting condition" and notify upper layers. This helps

AF_PACKET sockets cannot be written-to using select(), as they

a successful write, we have no other option but to start a timer
and re-try at a later time.
We will scale that timer based on the estimated duration of transmission

Similiar to the BSSGP layer prefix events with RX if it's an received PDU
or REQ if it's a request from the code.

A BLOCK message can be received when waiting for a UNBLOCK message
in state BLOCK

The vty should be able to block or unblock a specific NSVC.
Further more this case is special for the UNITDATA as those
can be still received until the other side response to the BLOCK PDU.

Usually talloc_free() and other free functions in osmocom allows
to be called with NULL which is then ignored.

Add a OSMO_ASSERT to all bind calls which doesn't
check if the bind is from the expected type.
The only exception is rx and tx functions (hot path).

At the moment libosmogb offers no convinient way to send RIM PDUs. Also
parsing an incoming RIM messages into destination, source routing
info and RIM container is not available.

The function bssgp_parse_rim_ri() and bssgp_create_rim_ri() are located
in gprs_bssgp.c, since there is now a gprs_bssgp_rim.c module it makes
more sense to put them there. Also adjust the code a bit so that its
more intuitive to read.

BSSGP RIM uses a number of nested containers to signal RIM application
specific payload information in a generic way. Lets add the container
structurs required for NACC.

Right now we end up in situations where only a NS-VC for data (BVCI != 0)
becomes unblocked, but the BSSGP and/or user application code is
notified that the NSE has recovered.
In the case of osmo-gbproxy, this will trigger a BVC-RESET on the
BVCI=0, but that obviously only works if the sig_weight > 0...

gprs_sn2_fr_connect2() is the same as gprs_ns2_fr_connect() with
the lookup-and-create-on-demand of the NSE first.
Rather than copy+paste, they should simply invoke each other.

The transfer cap call in ns2_prim_status_ind() asserts if
NSE is in an invalid state (nse is either alive or has NSVCS).

The local and remote entries should be cleared on SNS Size.
Further it can be cleared when SNS failed (e.g. all NSVC become dead)
so VTY doesn't show old entries before entering SNS Size.
