2023-09-18wifi: rtw89: 52c: rfk: disable DPK during MCCZong-Zhe Yang
DPK is one kind of RF calibration. When MCC (multi-channel concurrency) start/stop, DPK needs to do extra things to be off/on. We add a chanctx callback type, RTW89_CHANCTX_CALLBACK_RFK, and register it for RTL8852C to deal with DPK according to MCC states.

2023-09-18wifi: rtw89: rfk: disable driver tracking during MCCZong-Zhe Yang
After MCC (multi-channel concurrency) is started, FW will control channel changes and use the corresponding backup of RF calibration result. And, driver RF calibration (RF-K) won't be able to keep up with the speed at which the channels are changing. So, even if we keep tracking it in driver, the RF-K result might not be good either. To save these unnecessary things, we disable driver RF-K tracking during MCC.

2023-09-18wifi: rtw89: 52c: rfk: refine MCC channel info notificationZong-Zhe Yang
RF calibration will notify FW to backup the calibration result after it is done on a channel. For MCC (multi-channel concurrency) flow, when we at RTW89_ENTITY_MODE_MCC_PREPARE mode, RF calibration should execute on second channel of MCC, i.e. RTW89_SUB_ENTITY_1, and then, notify FW to backup the result for the second one. Originally, the RF calibration flow only fit single channel case. We are planning to support MCC on RTL8852C, so we refine its RF calibration flow to fit MCC case.

2023-09-18wifi: cw1200: Avoid processing an invalid TIM IEJeff Johnson
While converting struct ieee80211_tim_ie::virtual_map to be a flexible array it was observed that the TIM IE processing in cw1200_rx_cb() could potentially process a malformed IE in a manner that could result in a buffer over-read. Add logic to verify that the TIM IE length is large enough to hold a valid TIM payload before processing it.

Since commit 2d47c6956ab3 ("ubsan: Tighten UBSAN_BOUNDS on GCC"), UBSAN_BOUNDS no longer pretends 1-element arrays are unbounded.

2023-09-18net: stmmac: Tx coe sw fallbackRohan G Thomas
Add sw fallback of tx checksum calculation for those tx queues that don't support tx checksum offloading. DW xGMAC IP can be synthesized such that it can support tx checksum offloading only for a few initial tx queues. Also as Serge pointed out, for the DW QoS IP, tx coe can be individually configured for each tx queue. So when tx coe is enabled, for any tx queue that doesn't support tx coe with 'coe-unsupported' flag set will have a sw fallback happen in the driver for tx checksum calculation when any packets to be transmitted on these tx queues.
