   4 Subject: [PATCH 1/5] wifi: ath11k: fix band selection for ppdu received in
   5  channel 177 of 5 GHz
   6
   7 5 GHz band channel 177 support was added with the commit e5e94d10c856 ("wifi:
   8 ath11k: add channel 177 into 5 GHz channel list"). However, during processing
   9 for the received ppdu in ath11k_dp_rx_h_ppdu(), channel number is checked only
  10 till 173. This leads to driver code checking for channel and then fetching the
  11 band from it which is extra effort since firmware has already given the channel
  12 number in the metadata.
  13
  14 Fix this issue by checking the channel number till 177 since we support
  15 it now.
