UHD accepts optional 'args' that can be used for device descriptions such as IP address, device type, etc. Allow these to be passed in on the transceiver command line as the third argument (number of supported carriers is the second argument). This option benefits those who may have multiple UHD devices attached to a single system. This option is not yet supported by GSM core and requires starting the transceiver independently on the command line. This option has no effect when USRP1 is used.
