This patch series adds 6GHz frequency listing in ath11k driver and mac80211
registration for the 6GHz band. Also, extends some of wmi command tlvs for
supporting 6GHz.
In cfg80211, a new channel flag is added for identifying Preferred Scanning
Channels (PSC) in 6GHz band.
Pradeep Kumar Chitrapu (9):
cfg80211: Add new channel flag to identify 6GHz PSC channel
ath11k: add 6G frequency list supported by driver
ath11k: add support for 6GHz radio in driver
ath11k: Use freq instead of channel number in rx path
ath11k: extend peer_assoc_cmd for 6GHz band
ath11k: set psc channel flag when sending channel list to firmware.
ath11k: Add 6G scan dwell time parameter in scan request command
ath11k: Send multiple scan_chan_list messages if required
ath11k: Add support for 6g scan hint

2.17.1
With addition of 6Ghz channels, it is possible that wmi buffer size can
exceed the maximum wmi buffer size. So iterate over the channel list,
and send multiple messages till channel list is empty.
Also mark PSC channel flag for 6GHz channels accordingly.
