   4 Subject: [PATCH] wifi: rtw88: Extend rtw_debugfs_get_phy_info() for RTL8814AU
   5
   6 Print information about the 3rd and 4th RF paths and about the 3rd
   7 spatial stream.
   8
   9 Also, fix a small bug: don't show the average SNR and EVM for the OFDM
  10 and HT/VHT rates when the rate is actually CCK 11M.
