   4 Subject: [PATCH] wifi: rtw88: Fix rtw_desc_to_mcsrate() to handle MCS16-31
   5
   6 This function translates the rate number reported by the hardware into
   7 something mac80211 can understand. It was ignoring the 3SS and 4SS HT
   8 rates. Translate them too.
   9
  10 Also set *nss to 0 for the HT rates, just to make sure it's
  11 initialised.
