** For clusters with frequency table length greater than

** indicates, which set/part of frequency table the user is requesting.
** The set index value starts from zero. A set index value of 'Z',
** will fetch MSM_IOCTL_FREQ_SIZE or maximum available number of
** frequency values (if it is less than MSM_IOCTL_FREQ_SIZE)
** from the frequency table, starting from the index
** (Z * MSM_IOCTL_FREQ_SIZE).
** For example, in a device supporting 19 different frequencies, a set
** index value of 0 will fetch the first 16 (MSM_IOCTL_FREQ_SIZE)
** frequencies starting from the index 0 and a set value of 1 will fetch
** the remaining 3 frequencies starting from the index 16.
** A successful get, will populate the freq_table_len with the
** number of frequency table entries fetched.
