git://git.kernel.org/pub/scm/linux/kernel/git/wireless/wireless-next Kalle Valo says: ==================== wireless-next patches for v6.4 Most likely the last -next pull request for v6.4. We have changes all over. rtw88 now supports SDIO bus and iwlwifi continues to work on Wi-Fi 7 support. Not much stack changes this time. Major changes: cfg80211/mac80211 - fix some Fine Time Measurement (FTM) frames not being bufferable - flush frames before key removal to avoid potential unencrypted transmission depending on the hardware design iwlwifi - preparation for Wi-Fi 7 EHT and multi-link support rtw88 - SDIO bus support - RTL8822BS, RTL8822CS and RTL8821CS SDIO chipset support rtw89 - framework firmware backwards compatibility brcmfmac - Cypress 43439 SDIO support mt76 - mt7921 P2P support - mt7996 mesh A-MSDU support - mt7996 EHT support - mt7996 coredump support wcn36xx - support for pronto v3 hardware ath11k - PCIe DeviceTree bindings - WCN6750: enable SAR support ath10k - convert DeviceTree bindings to YAML * tag 'wireless-next-2023-04-21' of git://git.kernel.org/pub/scm/linux/kernel/git/wireless/wireless-next: (261 commits) wifi: rtw88: Update spelling in main.h wifi: airo: remove ISA_DMA_API dependency wifi: rtl8xxxu: Simplify setting the initial gain wifi: rtl8xxxu: Add rtl8xxxu_write{8,16,32}_{set,clear} wifi: rtl8xxxu: Don't print the vendor/product/serial wifi: rtw88: Fix memory leak in rtw88_usb wifi: rtw88: call rtw8821c_switch_rf_set() according to chip variant wifi: rtw88: set pkg_type correctly for specific rtw8821c variants wifi: rtw88: rtw8821c: Fix rfe_option field width wifi: rtw88: usb: fix priority queue to endpoint mapping wifi: rtw88: 8822c: add iface combination wifi: rtw88: handle station mode concurrent scan with AP mode wifi: rtw88: prevent scan abort with other VIFs wifi: rtw88: refine reserved page flow for AP mode wifi: rtw88: disallow PS during AP mode wifi: rtw88: 8822c: extend reserved page number wifi: rtw88: add port switch for AP mode wifi: rtw88: add bitmap for dynamic port settings wifi: rtw89: mac: use regular int as return type of DLE buffer request wifi: mac80211: remove return value check of debugfs_create_dir() ... ==================== Link: https://lore.kernel.org/r/20230421104726.800BCC433D2@smtp.kernel.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>
