Merge tag 'wireless-next-2023-03-30' of git://git.kernel.org/pub/scm/linux/kernel/git/wireless/wireless-next
Johannes Berg says: ==================== Major stack changes: * TC offload support for drivers below mac80211 * reduced neighbor report (RNR) handling for AP mode * mac80211 mesh fast-xmit and fast-rx support * support for another mesh A-MSDU format (seems nobody got the spec right) Major driver changes: Kalle moved the drivers that were just plain C files in drivers/net/wireless/ to legacy/ and virtual/ dirs. hwsim * multi-BSSID support * some FTM support ath11k * MU-MIMO parameters support * ack signal support for management packets rtl8xxxu * support for RTL8710BU aka RTL8188GU chips rtw89 * support for various newer firmware APIs ath10k * enabled threaded NAPI on WCN3990 iwlwifi * lots of work for multi-link/EHT (wifi7) * hardware timestamping support for some devices/firwmares * TX beacon protection on newer hardware * tag 'wireless-next-2023-03-30' of git://git.kernel.org/pub/scm/linux/kernel/git/wireless/wireless-next: (181 commits) wifi: clean up erroneously introduced file wifi: iwlwifi: mvm: correctly use link in iwl_mvm_sta_del() wifi: iwlwifi: separate AP link management queues wifi: iwlwifi: mvm: free probe_resp_data later wifi: iwlwifi: bump FW API to 75 for AX devices wifi: iwlwifi: mvm: move max_agg_bufsize into host TLC lq_sta wifi: iwlwifi: mvm: send full STA during HW restart wifi: iwlwifi: mvm: rework active links counting wifi: iwlwifi: mvm: update mac config when assigning chanctx wifi: iwlwifi: mvm: use the correct link queue wifi: iwlwifi: mvm: clean up mac_id vs. link_id in MLD sta wifi: iwlwifi: mvm: fix station link data leak wifi: iwlwifi: mvm: initialize max_rc_amsdu_len per-link wifi: iwlwifi: mvm: use appropriate link for rate selection wifi: iwlwifi: mvm: use the new lockdep-checking macros wifi: iwlwifi: mvm: remove chanctx WARN_ON wifi: iwlwifi: mvm: avoid sending MAC context for idle wifi: iwlwifi: mvm: remove only link-specific AP keys wifi: iwlwifi: mvm: skip inactive links wifi: iwlwifi: mvm: adjust iwl_mvm_scan_respect_p2p_go_iter() for MLO ... ==================== Link: https://lore.kernel.org/r/20230330205612.921134-1-johannes@sipsolutions.net Signed-off-by: Jakub Kicinski <kuba@kernel.org>
