git://git.kernel.org/pub/scm/linux/kernel/git/kvalo/ath ath.git patches for v6.8. We have new features only for ath12k but lots of small cleanup for ath10k, ath11k and ath12k. And of course smaller fixes to several drivers. Major changes: ath12k * support one MSI vector * WCN7850: support AP mode

2023-12-15Revert "wifi: ath12k: use ATH12K_PCI_IRQ_DP_OFFSET for DP IRQ"Karthikeyan Periyasamy1-4/+4
This reverts commit 1f1f7d548a00ebe50808cb1f580df9693e194a7c. The commit caused bootup failure on QCN9274 hw2.0 platform. Incorrect hardcode DP irq offset overwrite the CE irq, which caused the driver to miss the mandatory bootup message from the firmware through the CE interrupt. This occurs because the CE count differs between platforms. The revert has no impact since the original change was based on an incorrect assumption.

Trigger a RFK (RF calibration) in firmware by a H2C command, and in progress it reports log and a result finally by C2H events. Firstly, add prototype of the C2H event handlers to have a simple picture of framework. The callers who trigger H2C will wait until a C2H event is received, so we must process these C2H events in receiving process. Thus, mark this kind of C2H events as atomic. Also, timestamp is also useful for debugging, mark C2H events carrying RFK log as atomic as well.

AP BSSID configuration is missing at AP start. Without this fix, FW returns STA interface MAC address after first init. When hostapd restarts, it gets MAC address from netdev before driver sets STA MAC to netdev again. Now MAC address between hostapd and net interface are different causes STA cannot connect to AP. After that MAC address of uap0 mlan0 become the same. And issue disappears after following hostapd restart (another issue is AP/STA MAC address become the same). This patch fixes the issue cleanly.

2023-12-12wifi: cfg80211: add BSS usage reportingJohannes Berg5-35/+195
Sometimes there may be reasons for which a BSS that's actually found in scan cannot be used to connect to, for example a nonprimary link of an NSTR mobile AP MLD cannot be used for normal direct connections to it. Not indicating these to userspace as we do now of course avoids being able to connect to them, but it's better if they're shown to userspace and it can make an appropriate decision, without e.g. doing an additional ML probe. Thus add an indication of what a BSS can be used for, currently "normal" and "MLD link", including a reason bitmap for it being not usable. The latter can be extended later for certain BSSes if there are other reasons they cannot be used.

2023-12-12wifi: iwlwifi: remove async command callbackJohannes Berg8-82/+39
There's only one user of this code, which is STA unblock during sleep for uAPSD on really old devices. Instead of having this all through the API with calls up and down, just implemented a special-case CMD_BLOCK_TXQS flag for this, it's only needed in the old gen1 transport. While at it, fix a complain that lockdep would have, as we lock the cmd queue and then the TXQs in the reclaim by using spin_lock_nested(). We no longer need to disable BHs in iwl_trans_pcie_block_txq_ptrs() since it's called with them disabled already.
