[Bug 2084731] Re: Not report 6 GHz capability correctly

[Dirk Su]

** Description changed:

  [Impact]
  
  network-manager not report 6GHz capability even hardware able to support
  6GHz band
  
  [Test Plan]
  
  1. nmcli -f wifi-properties.6ghz device show $DEV
  2. should get correct result on 6GHz band enabled system
     "WIFI-PROPERTIES.6GHZ:                   yes"
  
  [Where problems could occur]
- This SRU add attribute NL80211_ATTR_SPLIT_WIPHY_DUMP to split wiphy data across multiple messages, then parse the message one by one to get full supported frequencies. This attribute added after Linux 3.9. And there is not other function impact. The risk should be low
+ If the parsing is incorrect, the status of WIFI-PROPERTIES.2GHZ, WIFI-PROPERTIES.5GHZ and WIFI-PROPERTIES.6GHZ may be incorrect.
