Research direction
Start with modem_support.json and compare the EM7455 entry added by following the MC7354 information. Reproduce the dial-up flow and review the attached evidence to identify why the network interface does not receive an IP address. Done means the EM7455 is recognized and obtains an IP address successfully after dialing.
