This branch series implements the usage of the F1 Setup Request internally at the gNB, even if CU and DU run in the same process. Until now, the F1 Setup Request contained struct fields to pass IP configuration to the F1AP module; this information is not necessary in monolithic, nor should it be relevant when passing the information in F1 Setup Request. Therefore, this commit moves all IP connection-related information out of the F1 Setup Request and into a separate structure instead. In order to give the F1AP module the necessary connection information, the DU_REGISTER_REQ message is introduced that combines the F1 Setup Request and IP configuration, such that the F1AP module can setup the SCTP connection and then send the F1 Setup Request message. In a later commit, there will be a callback for F1 Setup Request at MAC to simply register the DU at the CU. The monolithic callback will simply forward the F1 Setup Request The F1AP callback will look up the IP configuration and create DU_REGISTER_REQ message containing IP configuration and F1 Setup Request, which is then handled by the F1AP module. To this end, a separate function in gnb_config.c allows to read IP information from configuration.

Instead of storing the F1 Setup Request implicitly in F1 context, we provide the F1 Setup Request message to be encoded explicitly to the encoding function.

We ever only have one instance, so hard code that.

In the case of MIMO, we reused memory to point to the same PUCCH resource. This is problematic, since ASN_STRUCT_FREE() would try to free this resource twice. This commit changes to create distinct memory for the PUCCH resources, while putting the same configuration to still use the same PUCCH resource from a radio configuration point of view.

This time constant plays a major role in how long a UE has to wait maximally before it might be scheduled. For instance, if a UE had a lot of traffic, the average traffic will be high, pushing the PF coefficient down. If another UE with no traffic in the past becomes active with heavy traffic, the first UE might not be scheduled for an extended period of time. In the AW2S-Amarisoft UE CI test pipeline, we sometimes see that the maximum number of RLC retransmissions was reached. While this might not be the (only) cause, scheduling a UE more often might prevent such situations, and we saw an improved stability.
