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 helper function is added for identifying Preferred Scanning
Channels (PSC) in 6GHz band.
changes in v3:
- cfg80211: remove PSC channel flag and instead add helper function.
- Address differences in 6GHZ frequencies between IEEE P802.11ax/D6.0
and IEEE P802.11ax/D6.1
changes in v2:
- Fixed ath11k_phymode to be set in 6GHZ band
Pradeep Kumar Chitrapu (9):
cfg80211: Add helper function 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

6GHz channels are divided into preferred scanning channels(PSC)
and non-PSC channels. One in every four 20MHz channels is a PSC.
Spec mandates to use only PSC channels as primary channels for
setting up BSS on 6GHz only AP.
The set of 20 MHz channels in the 6 GHz band, with channel center
frequency, ch_a = Channel starting frequency – 55 + 80 × n (MHz)
are referred to as preferred scanning channels (PSCs) where,
n = 1, …, 15 as per IEEE P802.11ax/D6.1.
This function can be used by drivers or cfg80211 when making
scanning decision on 6GHz channels.

v3:
- update channel starting frequency from 5945 to 5950 as per

{
int chan_num =
ieee80211_frequency_to_channel(chan->center_freq);
return chan->band == NL80211_BAND_6GHZ && chan_num % 16 == 5;
}
Apart from the naming, where I guess I prefer actually
cfg80211_channel_is_psc()
or so, does that seem reasonable to you? I'd prefer not to hardcode
frequencies everywhere, so in that regard I like our version better.
Maybe bail out earlier if band != 6 ghz:
static inline bool cfg80211_channel_is_psc(struct ieee80211_channel *chan)
{
if (chan->band != NL80211_BAND_6GHZ)
return false;
return ieee80211_frequency_to_channel(chan->center_freq) % 16 == 5;
}

As 6GHz cahnnel numbers overlap with those of 5GHz and 2GHz bands,
it is necessary to use frequency when determining the band info
in rx path.

This adds support required for configuring min_data_rate of 6GHz oper IE
and peer_he_caps_6ghz in peer assoc command. The Minimum Rate field
indicates the minimum rate, in units of 1 Mb/s, that the non-AP STA is
allowed to use for sending PPDUs as defined in IEEE P802.11ax™/D6.0.

If 6 ghz channel is a Preferred Scanning Channel(PSC), mark
the channel flag accordingly when updating channel list to firmware.
This will be used when making scanning decision in 6GHz channels.
Signed-off-by: Pradeep Kumar Chitrapu <pradeepc@codeaurora.org>

v3:
- use helper function ieee80211_is_channel_psc() instead of
channel flag for identifying 6GHz PSC channels.

If 6 ghz channel is a Preferred Scanning Channel(PSC), mark
the channel flag accordingly when updating channel list to firmware.
This will be used when making scanning decision in 6GHz channels.
Signed-off-by: Pradeep Kumar Chitrapu <pradeepc@codeaurora.org>

v3:
- use helper function ieee80211_is_channel_psc() instead of
channel flag for identifying 6GHz PSC channels.

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.
