nanoBTS with newer firmware (patch)

Hi list,

I just had tried to connect a nanoBTS model 165a with firmware v142b13d0 to openBSC. The BTS does connect to OML, starts with the PING - PONG and identifies itself, but nothing else happens (i.e. no software activate request). As recent firmware requires an explict IDENTITY ACK after answering an IDENTITY REQ with the RESP, I made a small patch to ipaccess.c - and voila, BTS connects OML, gets initalised (at the second attempt as usual - I'll try to dig into this later), establishes RSL and is happily showing green.

Feel free to integrate the attached patch.

Best regards,

Flo.
