wifi: ath12k: enable IEEE80211_HW_SINGLE_SCAN_ON_ALL_BANDS for WCN7850
Currently mac80211 will send 3 scan request for each scan of WCN7850, they
are 2.4 GHz/5 GHz/6 GHz band scan. Firmware of WCN7850 will cache the RNR
IE(Reduced Neighbor Report element) which exist in the beacon of 2.4 GHz/5
GHz of the AP which is co-located with 6 GHz, and then use the cache to
scan in 6 GHz band scan if the 6 GHz scan is in the same scan with the 2.4
GHz/5 GHz band, this will helpful to search more AP of 6 GHz. Also it will
decrease the time cost of scan because firmware will use dual-band scan
for the 2.4 GHz/5 GHz, it means the 2.4 GHz and 5 GHz scans are doing
simultaneously.
Set the flag IEEE80211_HW_SINGLE_SCAN_ON_ALL_BANDS for WCN7850 since it
supports 2.4 GHz/5 GHz/6 GHz in a single wiphy/ieee80211_hw.
This does not impact QCN9274, because it is not single_phy, so does not
have 2.4 GHz/5 GHz/6 GHz in the same wiphy, then it does not match the
condition and then IEEE80211_HW_SINGLE_SCAN_ON_ALL_BANDS will not set for
QCN9274.
Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0-03427-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1.15378.4
