Currently wiphy level configurations like RTS threshold, lacks radio level get/set support and same value is applied to all radios of wiphy. Add support to parse radio id attribute and use the same to apply the configuration to corresponding radio of a multi radio wiphy. This design will not disturb the global wiphy configuration. If radio id is not passed from userspace, then the existing design of setting attribute to all the radios will hold good. Also add support to get the radio specific attributes in a multi-radio wiphy from userspace. The attributes that can be handled for each radio are: NL80211_ATTR_WIPHY_TX_POWER_LEVEL NL80211_ATTR_WIPHY_ANTENNA_TX NL80211_ATTR_WIPHY_ANTENNA_RX NL80211_ATTR_WIPHY_RETRY_SHORT NL80211_ATTR_WIPHY_RETRY_LONG NL80211_ATTR_WIPHY_FRAG_THRESHOLD NL80211_ATTR_WIPHY_RTS_THRESHOLD NL80211_ATTR_WIPHY_COVERAGE_CLASS NL80211_ATTR_TXQ_LIMIT NL80211_ATTR_TXQ_MEMORY_LIMIT NL80211_ATTR_TXQ_QUANTUM With this design, the new userspace designed to set/get per-radio parameters can work with both traditional and multi-radio wiphys. v14: - Fixed errors and warnings reported by kernel test bot. v13: - Fixed errors and warnings reported by kernel test bot. v12: - Added a patch to introduce a new NL attribute - NL80211_ATTR_WIPHY_RADIO_INDEX. - Modified the APIs handling per-radio attributes to take radio index from the userspace. v11: - Resolved warning flagged by clang compiler. v10: - Modified data type of radio_id to int. - Resolved memory leak. v9: - Fixed errors reported by patchwork's wifibot. v8: - Fixed warning reported by kernel test bot regarding variable initialization. v7: - Addressed cosmetic comments from Johannes Berg. - Removed patches - wifi: cfg80211: set tx power per radio in a wiphy and wifi: mac80211: set tx power per radio in a wiphy. v6: - Fixed warning reported by kernel test bot. v5: - Changed default value of radio id from 0xff to -1. - Changed driver callback order for global wiphy parameters. - Fixed other minor comments related to code-cleanup. v4: - Fixed stack frame size warning. - Added S-O-B tag in patches 4/5 and 5/5. v3: - Fixed warnings to refresh copyright, to curb long lines of code and to include kernel documentation for a few variables. v2: - Converted the series to [PATCH] from [PATCH RFC], link to which is, https://patchwork.kernel.org/project/linux-wireless/cover/20250107182506.1838704-1-quic_ramess@xxxxxxxxxxx/ Roopni Devanathan (4): wifi: cfg80211/mac80211: Add support to get radio index wifi: cfg80211: Add Support to Set RTS Threshold for each Radio wifi: cfg80211: Report per-radio RTS threshold to userspace wifi: mac80211: Set RTS threshold on per-radio basis drivers/net/wireless/admtek/adm8211.c | 2 +- drivers/net/wireless/ath/ar5523/ar5523.c | 5 +- drivers/net/wireless/ath/ath10k/core.c | 2 +- drivers/net/wireless/ath/ath10k/hw.c | 1 + drivers/net/wireless/ath/ath10k/hw.h | 2 +- drivers/net/wireless/ath/ath10k/mac.c | 19 ++-- drivers/net/wireless/ath/ath11k/mac.c | 14 ++- drivers/net/wireless/ath/ath12k/mac.c | 14 ++- drivers/net/wireless/ath/ath5k/mac80211-ops.c | 12 ++- drivers/net/wireless/ath/ath6kl/cfg80211.c | 7 +- drivers/net/wireless/ath/ath9k/htc_drv_main.c | 10 +- drivers/net/wireless/ath/ath9k/main.c | 9 +- drivers/net/wireless/ath/carl9170/main.c | 2 +- drivers/net/wireless/ath/wcn36xx/main.c | 5 +- drivers/net/wireless/ath/wil6210/cfg80211.c | 3 +- drivers/net/wireless/atmel/at76c50x-usb.c | 2 +- drivers/net/wireless/broadcom/b43/main.c | 6 +- .../net/wireless/broadcom/b43legacy/main.c | 2 +- .../broadcom/brcm80211/brcmfmac/cfg80211.c | 8 +- .../broadcom/brcm80211/brcmsmac/mac80211_if.c | 3 +- drivers/net/wireless/intel/iwlegacy/common.c | 2 +- drivers/net/wireless/intel/iwlegacy/common.h | 2 +- drivers/net/wireless/intel/iwlwifi/dvm/agn.h | 2 +- drivers/net/wireless/intel/iwlwifi/dvm/rxon.c | 2 +- .../net/wireless/intel/iwlwifi/mld/mac80211.c | 6 +- .../net/wireless/intel/iwlwifi/mvm/mac80211.c | 9 +- drivers/net/wireless/intel/iwlwifi/mvm/mvm.h | 12 ++- drivers/net/wireless/intersil/p54/main.c | 3 +- .../net/wireless/marvell/libertas_tf/main.c | 2 +- .../net/wireless/marvell/mwifiex/cfg80211.c | 11 ++- drivers/net/wireless/marvell/mwl8k.c | 12 ++- drivers/net/wireless/mediatek/mt76/mac80211.c | 3 +- drivers/net/wireless/mediatek/mt76/mt76.h | 3 +- .../net/wireless/mediatek/mt76/mt7603/main.c | 5 +- .../net/wireless/mediatek/mt76/mt7615/main.c | 11 ++- .../net/wireless/mediatek/mt76/mt76x0/main.c | 2 +- .../wireless/mediatek/mt76/mt76x0/mt76x0.h | 2 +- drivers/net/wireless/mediatek/mt76/mt76x02.h | 4 +- .../net/wireless/mediatek/mt76/mt76x02_util.c | 4 +- .../wireless/mediatek/mt76/mt76x2/pci_main.c | 6 +- .../wireless/mediatek/mt76/mt76x2/usb_main.c | 2 +- .../net/wireless/mediatek/mt76/mt7915/main.c | 13 ++- .../net/wireless/mediatek/mt76/mt7921/main.c | 8 +- .../net/wireless/mediatek/mt76/mt7925/main.c | 8 +- drivers/net/wireless/mediatek/mt76/mt792x.h | 3 +- .../net/wireless/mediatek/mt76/mt792x_core.c | 3 +- .../net/wireless/mediatek/mt76/mt7996/main.c | 11 ++- drivers/net/wireless/mediatek/mt7601u/main.c | 5 +- .../wireless/microchip/wilc1000/cfg80211.c | 7 +- drivers/net/wireless/purelifi/plfxlc/mac.c | 5 +- .../net/wireless/quantenna/qtnfmac/cfg80211.c | 8 +- .../net/wireless/ralink/rt2x00/rt2800lib.c | 2 +- .../net/wireless/ralink/rt2x00/rt2800lib.h | 3 +- drivers/net/wireless/ralink/rt2x00/rt2x00.h | 8 +- .../net/wireless/ralink/rt2x00/rt2x00mac.c | 8 +- .../wireless/realtek/rtl818x/rtl8180/dev.c | 2 +- .../wireless/realtek/rtl818x/rtl8187/dev.c | 2 +- drivers/net/wireless/realtek/rtl8xxxu/core.c | 8 +- drivers/net/wireless/realtek/rtlwifi/core.c | 2 +- drivers/net/wireless/realtek/rtw88/mac80211.c | 9 +- drivers/net/wireless/realtek/rtw88/main.h | 2 +- drivers/net/wireless/realtek/rtw88/rtw8822b.c | 1 + drivers/net/wireless/realtek/rtw88/rtw8822c.c | 1 + drivers/net/wireless/realtek/rtw89/mac80211.c | 10 +- drivers/net/wireless/rsi/rsi_91x_mac80211.c | 9 +- drivers/net/wireless/silabs/wfx/sta.c | 4 +- drivers/net/wireless/silabs/wfx/sta.h | 4 +- drivers/net/wireless/st/cw1200/sta.c | 5 +- drivers/net/wireless/st/cw1200/sta.h | 5 +- drivers/net/wireless/ti/wl1251/main.c | 5 +- drivers/net/wireless/ti/wlcore/main.c | 8 +- drivers/net/wireless/virtual/mac80211_hwsim.c | 6 +- drivers/net/wireless/zydas/zd1211rw/zd_mac.c | 2 +- .../staging/rtl8723bs/os_dep/ioctl_cfg80211.c | 6 +- include/net/cfg80211.h | 30 +++++- include/net/mac80211.h | 17 ++-- include/uapi/linux/nl80211.h | 12 +++ net/mac80211/cfg.c | 37 +++++--- net/mac80211/chan.c | 2 +- net/mac80211/driver-ops.h | 36 ++++---- net/mac80211/ieee80211_i.h | 5 +- net/mac80211/iface.c | 6 +- net/mac80211/main.c | 9 +- net/mac80211/mlme.c | 12 +-- net/mac80211/offchannel.c | 2 +- net/mac80211/pm.c | 2 +- net/mac80211/trace.h | 78 ++++++++++++---- net/mac80211/tx.c | 4 +- net/mac80211/util.c | 24 +++-- net/wireless/core.c | 19 ++++ net/wireless/nl80211.c | 92 +++++++++++++++++-- net/wireless/rdev-ops.h | 39 ++++---- net/wireless/trace.h | 79 +++++++++++----- net/wireless/wext-compat.c | 10 +- 94 files changed, 638 insertions(+), 293 deletions(-) base-commit: ea15e046263b19e91ffd827645ae5dfa44ebd044 -- 2.25.1
