   4 Subject: [PATCH] wifi: ath11k: add parsing of phy bitmap for reg rules
   5
   6 Certain regulatory domains could put restrictions on phy mode operation.
   7 For example, in a few countries HE Operation is not allowed. For such
   8 countries, firmware indicates this via phy bitmap in each reg rule.
   9
  10 Currently, there is no logic to parse this info and then pass it on to the
  11 cfg80211/regulatory.
  12
  13 Add parsing of this phy bitmap from the regulatory channel change event and
  14 then accordingly map it to cfg80211/regulatory flags and pass it on to it.
  15
  16 While at it, correct typo in debug print s/dsf/dfs.
