[SR-Users] Dynamic CSEQ Updates

[Daniel-Constantin Mierla]

Hello,

the callbacks are in the code, executed just after receiving and before
sending to the network, I don't think there is no possibility to
interact with the callbacks from the config file.

Having the possibility to turn on/off the cseq update likely requires
some C coding, I don't remember by heart any way to do it right now, but
I haven't had the time to check the code and refresh how is done to see
if any workaround can be used at this moment.

Cheers.
Daniel
