[PATCH 1/3] ath11k: re-enable ht_cap/vht_cap for 5G band for WCN6855

[Jouni Malinen]

From: Wen Gong <wgong@codeaurora.org>

WCN6855 uses single_pdev_only, so it supports both the 5G and 6G bands
in the same ath11k/pdev and it needs to enable ht_cap/vht_cap for the 5G
band, otherwise it will downgrade to non-HT mode for the 5G band. Some
chips like QCN9074 only support the 6G band, not the 5G band, and use
the flag ar->supports_6ghz which is true to discard ht_cap/vht_cap.

[PATCH 2/3] ath11k: enable 6G channels for WCN6855

[Jouni Malinen]

From: Wen Gong <wgong@codeaurora.org>

For some chips such as WCN6855, single_pdev_only is set in struct
ath11k_hw_params which means ath11k calls ieee80211_register_hw() only
once and create only one device interface, and that device interface
supports all 2G/5G/6G channels.

ath11k_mac_setup_channels_rates() sets up the channels and it is called
for each device interface. It is called only once for single_pdev_only,
and then set up all channels for 2G/5G/6G. The logic of
ath11k_mac_setup_channels_rates() is not suitable for single_pdev_only,
it leads to all 6G channels being disabled for the device interface
which is single_pdev_only such as WCN6855.

Add channel frequency checks for the 6G band and enable the 6G channels
properly based on what is supported by the chip.

[PATCH 3/3] ath11k: copy cap info of 6G band under WMI_HOST_WLAN_5G_CAP for WCN6855

[Jouni Malinen]

From: Wen Gong <wgong@codeaurora.org>

WCN6855 has 2 phys, one is 2G, another is 5G/6G, so it should copy the
cap info of 6G band under the check of WMI_HOST_WLAN_5G_CAP as well as
for the 5G band. Some chips like QCN9074 only have 6G, not have 2G and
5G, and this 6G capability is also under WMI_HOST_WLAN_5G_CAP, so this
change will not disturb it.
