rtw-next patches for v6.11 Some cleanups of rtl8xxxu and rtlwifi, and some fixes of rtw88. The major change is to develop WoWLAN and preparation of RTL8852BE-VT listed below: rtw89: - preparation of RTL8852BE-VT * add RF calibration code * move shared code with RTL8852BE to common module - add WoWLAN for WiFi 6 chips - support 36-bit PCI DMA
2024-07-05wifi: rtw89: Fix array index mistake in rtw89_sta_info_get_iter()Aleksandr Mishin
In rtw89_sta_info_get_iter() 'status->he_gi' is compared to array size. But then 'rate->he_gi' is used as array index instead of 'status->he_gi'. This can lead to go beyond array boundaries in case of 'rate->he_gi' is not equal to 'status->he_gi' and is bigger than array size. Looks like "copy-paste" mistake. Fix this mistake by replacing 'rate->he_gi' with 'status->he_gi'. Found by Linux Verification Center (linuxtesting.org) with SVACE.

2024-07-05wifi: rtw89: unify the selection logic of RFK table when MCCZong-Zhe Yang
Driver will notify FW the target index of RFK table to use at some moments. When MCC (multi-channel concurrent), the correctness of the notification is especially important. We now unify the selection logic of RFK table as below among chips. 1. check each table if it matches target channel 2. check all tables if any is idle by iterating active channels 3. replace the first table if all are busy unexpectedly Signed-off-by: Zong-Zhe Yang <kevin_yang@realtek.com> Signed-off-by: Ping-Ke Shih <pkshih@realtek.com> Link: https://patch.msgid.link/20240702124452.18747-2-pkshih@realtek.com

2024-05-23wifi: rtw89: fix HW scan not aborting properlyPo-Hao Huang
There is a length limit on the commands we send to firmware, so dividing to two commands is sometimes required when scanning. When aborting scan, we should not send second scan command to firmware after the first one is finished. This could cause some unexpected errors when we cannot receive firmware events (e.g. in suspend). Another case is scan happens before suspending, ieee80211_do_stop() is called to abort scan and driver indicate scan completion by ieee80211_scan_completed(), which queues event to scan work. But scan work might be late to execute after ieee80211_do_stop(). To correct this, driver indicates ieee80211_scan_completed() before returning, so that ieee80211_do_stop() can flush scan work properly.
