Hello osmith, Jenkins Builder, laforge, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/osmo-bsc/+/25408 to look at the new patch set (#4). Change subject: Support Neighbor Address Resolution over PCUIF IPA multiplex ...................................................................... Support Neighbor Address Resolution over PCUIF IPA multiplex While NACC was initially developed, it became clear there was need for a way to interact PCU<->BSC in order resolve ARFCN+BSIC into CGI-PS for later RIM usage. Hence, this resolution was first (until today) implemented using an out of bands RPC system using the CTRL interface, which required specific config to be written and matches in osmo-pcu and osmo-bsc VTY (ip+port of the CTRL interface to use). However, this has several shortcomings: * As explained above, specific configuration is required * Since recently, we do support BSC redundancy in osmo-bts. Hence the BTS may switch to a BSC other than first one. If that happened, that'd mean the CTRL interface would still point to the initially configured one, which may not be the same currently serving the PCU. During recent development of ANR related features, a similar need for PCU<->BSC was required, but this time it was decided to extend the IPA multiplex of the Abis OML connection to pass PCUIF messages, transparently forwarded to each side by the BTS. This has the advantage that connection PCU<->BTS is handled by BTS and both sides send messages transparently. Let's switch by default to using this new interface, while still maintaing the old way for a while (announcing them as deprecated) to avoid breaking existing deployments until they are upgraded to new versions of osmo-pcu and osmo-bsc.
