mgcp: Attempt to separate the RTP/RTCP port for the Network and for the BTS
...
We plan to have two different ports for the network and for the
BTS to avoid detecting the BTS and to dynamically allocate the
port to have old data not go to a new socket.

mgcp: Attempt to count missing RTP packets with a basic calculation
...
This code compares the UDP sequence numbers of two RTP messages
and guesses if packets are missing. It is guessing in two ways:
1.) by default the sequence number is 0, so on the first
value we ignore the jump... we might ignore a real issue
in case of a wrap around which is easily possible as the
sequence should be a random number.
2.) the UDP stream might have been reordered on the network
and we would see the jump...
In any case these two shortcomings are acceptable for the feature
that is meant to provide some basic analysis..

mgcp: Rename TOS to DSCP

DSCP is the more modern information for TOS and the kernel
will set parts of TOS by itself (e.g. for ECN).

[mgcp] Ignore every dummy packet...
...
This routine should operate on different packets and the
dummy load is smaller than a legitimate RTP header so it
is unlikely we will filture out genuine traffic.
The reason is the dummy load might be send more than once.

This can be used by higher level code to send one dummy
message from the audio port to the network. This can be
used to make the remote discover the nated port of this
endpoint.

...
This change separates the protocol from the actual network code
(bind, forward data). This will allow to more easily hook up the
RTP code from OpenBSC and to not use local sockets at all.
