Remove netlink code, and the PDCP_USE_NETLINK macro, as there is no known use, it makes the code more complicated, and is simply "technical debt". In 4G PDCP, a subtle change has been introduced, in pdcp_module_init() of pdcp.c. Looking at the diff of this commit, it can be seen that there is now a new "else-if (ENB_NAS_USE_TUN_W_MBMS_BIT)" branch that is under what was the "if (PDCP_USE_NETLINK)" branch, while the code fragment was actually inside the "else" branch of PDCP_USE_NETLINK. This seems to be necessary: previously, if we did not use noS1 mode and we don't use any TUN (i.e., the eNB), the else block would set up this interface. It is important that this interface is brought up, because if we omit it, RFsim will not work. It seems to me that this interface will regularly create some traffic; without it, RFsim will be blocked, and the UE cannot connect. In short, it seems to be important to have the MBMS interface, which injects traffic in the RFsim side, which will unblock RFsim. The change in pdcp_module_init() preserves the total changes of the if-else (PDCP_USE_NETLINK).
