   4 Subject: [PATCH 1/2] wifi: ath12k: Pass correct values of center freq1 and
   5  center freq2 for 160 MHz
   6
   7 Currently, for 160 MHz bandwidth, center frequency1 and
   8 center frequency2 are not passed correctly to the firmware.
   9 Set center frequency1 as the center frequency
  10 of the primary 80 MHz channel segment and center frequency2 as
  11 the center frequency of the 160 MHz channel and pass the values
  12 to the firmware.
