Hello Jenkins Builder, dexter, laforge, neels,

I'd like you to reexamine a change. Please visit

https://gerrit.osmocom.org/c/osmo-hnbgw/+/35168?usp=email

to look at the new patch set (#2).

The following approvals got outdated and were removed: Code-Review+1 by laforge, Verified+1 by Jenkins Builder

Change subject: mgw_fsm: Modify RAB on HNB if IuUP local IP addr at MGW changes during MDCX ......................................................................

mgw_fsm: Modify RAB on HNB if IuUP local IP addr at MGW changes during MDCX

Allow IP address renegotation between HNB and MGW: * Upon MGCP MDCX ACK received from the RAN-side conn, if the IP address/port changes, then restart the RAB-Ass-Req+Resp procedure on Iuh. * Upon RAB-Ass-Resp received from the HNB, if the IP address/port changes, then go through another MDCX + MDCX ACK prcoedure on MGCP.

An MDCX counter is introduced to avoid infinite loops where the HNB and the MGW keep changing their IP address triggered by the change on the other side, eg. due to incorrect network/routing setup. The counter is also used to track count in order to make sure that always at least 1 MDCX is transmitted, in order to change conn_mode to SEND_RECV.
