This adds a feature to patch the BSSGP MNC/MCC fields of messages going
to and coming from the SGSN. To enable this feature, the gbproxy's
VTY commands 'core-mobile-country-code' and/or
'core-mobile-network-code' must be used. All packets to the SGSN are
patched to match the configured values. Packets received from the
SGSN are patched to the corresponding values as last seen from the BSS
side.
Note that this will probably not work with a gbproxy used for several
BSS simultaneously.
Note also, that MCC/MNC contained in a LLC IE will not be patched.
