In e1_send_bearer_updates(), we send the DL (DU) TEID and address to the CU-UP. Therefore, correct the variable names to reflect that the F1-U information pertains to the DU. Also, move the tunnel info update function f1u_dl_gtp_update() to a more prominent place, and take the pointer to the struct containing the "interesting" information.
