The prerequisite for MLO support in cfg80211/mac80211 is that all the links participating in MLO must be from the same wiphy/ieee80211_hw. To meet this expectation, some drivers may need to group multiple discrete hardware each acting as a link in MLO under single wiphy. So it required to have some sort of mapping while describing interface combination capabilities for each of the underlying physical hardware. This patch set tries to add an infrastructure to advertise underlying hw specific capabilities like channel and interface combinations. Some of the todos - More than one concurrent monitor mode support each operating on different channels under one ieee80211_hw - Mechanism for each underlying radio specific configurations like txpower, channel, etc. RFC series Link: https://lore.kernel.org/linux-wireless/20220920100518.19705-1-quic_vthiagar@xxxxxxxxxxx/ Harshitha Prem (1): wifi: ath12k: Advertise multi hardware iface combination Karthikeyan Periyasamy (1): wifi: ath12k: Introduce iface combination cleanup helper Vasanthakumar Thiagarajan (11): wifi: cfg80211: Add provision to advertise multiple radio in one wiphy wifi: nl80211: send underlying multi-hardware channel capabilities to user space wifi: cfg80211: Refactor the interface combination limit check wifi: cfg80211/mac80211: extend iface comb advertisement for multi-hardware dev wifi: nl80211: Refactor the interface combination limit check wifi: nl80211: send iface combination to user space in multi-hardware wiphy wifi: cfg80211/mac80211: Refactor iface comb iterate callback for multi-hardware dev wifi: cfg80211: Refactor the iface combination iteration helper function wifi: cfg80211: Add multi-hardware iface combination support wifi: mac80211: expose channel context helper function wifi: mac80211: Add multi-hardware support in the iface comb helper drivers/net/wireless/ath/ath12k/mac.c | 147 +++++++++++- include/net/cfg80211.h | 175 +++++++++++++- include/uapi/linux/nl80211.h | 78 ++++++- net/mac80211/chan.c | 35 ++- net/mac80211/ieee80211_i.h | 5 +- net/mac80211/main.c | 46 ++++ net/mac80211/util.c | 196 ++++++++++++++-- net/wireless/core.c | 294 +++++++++++++++++++---- net/wireless/nl80211.c | 154 ++++++++++-- net/wireless/util.c | 321 ++++++++++++++++++++++---- 10 files changed, 1318 insertions(+), 133 deletions(-) base-commit: d69aef8084cc72df7b0f2583096d9b037c647ec8 -- 2.34.1
