   4 Subject: [PATCH] wifi: rtw88: Extend rtw_debugfs_get_tx_pwr_tbl() for
   5  RTL8814AU
   6
   7 Make it print the TX power details for all RF paths, not just A and B,
   8 and for all the rates supported by the chip, not just 1SS and 2SS
   9 rates.
  10
  11 Also skip the RF paths and rates not supported by the chip.
