upf not using SBI interface for communicating with NRF
Suppose I use a dedicated interface for N4 and SBI. UPF is not using the SBI interface to communicate with NRF. It still uses the old spgwu methodology of N4 for communicating with NRF. I think it is because of this --> https://gitlab.eurecom.fr/oai/cn5g/oai-cn5g-upf/-/blob/develop/src/upf_app/app/upf_nrf.cpp?ref_type=heads#L300.
In SMF logs I see
[2023-09-03 21:25:42.515] [smf_app] [info] UPF Interface list is empty: Assume that the UPF has a N3 and a N6 interface.
[2023-09-03 21:25:42.515] [smf_app] [info] UPF Interface list is empty: Assume that the UPF has a N3 and a N6 interface.
And upf profile for registering to NRF
{"capacity":100,"fqdn":"","heartBeatTimer":50,"ipv4Addresses":["10.244.0.121"],"nfInstanceId":"c09ee836-f536-47a1-a243-0a3ec50466e6","nfInstanceName":"OAI-UPF","nfStatus":"REGISTERED","nfType":"UPF","priority":1,"sNssais":[{"sd":"16777215","sst":1}],"upfInfo":{"sNssaiUpfInfoList":[{"dnnUpfInfoList":[{"dnn":"oai"}],"sNssai":{"sd":"16777215","sst":1}}]}}
Shouldn't there be information for n3?
