gsm_config and gsm_netconfig includes unused fields that have been included to allow future extension without changing the structure size. Unfortunately, no checks have been included for these field. The actual value set by old user space code remains undefined. This means that future extensions can not use these fields without breaking old user space code which may set unexpected values. Mark these fields accordingly to avoid breaking code changes.
