wifi: mac80211: add NAN peer schedule support

2026-04-07T13:36:03+00:00

Peer schedules specify which channels the peer is available on and when. Add support for configuring peer NAN schedules: - build and store the schedule and maps - for each channel, make sure that it fits into the capabilities, and take the minimum between it and the local compatible nan channel. - configure the driver Note that the removal of a peer schedule should be done by the driver upon NMI station removal.

wifi: mac80211: Add eMLSR/eMLMR action frame parsing support

2026-02-02T09:11:18+00:00

Introduce support in AP mode for parsing of the Operating Mode Notification frame sent by the client to enable/disable MLO eMLSR or eMLMR if supported by both the AP and the client. Add drv_set_eml_op_mode mac80211 callback in order to configure underlay driver with eMLSR/eMLMR info.

wifi: mac80211: fix incorrect type for ret

2025-08-26T11:46:48+00:00

The variable ret is declared as a u32 type, but it is assigned a value of -EOPNOTSUPP. Since unsigned types cannot correctly represent negative values, the type of ret should be changed to int.

wifi: mac80211: don't send keys to driver when fips_enabled

2025-07-15T09:00:38+00:00

When fips_enabled is set, don't send any keys to the driver (including possibly WoWLAN KEK/KCK material), assuming that no device exists with the necessary certifications. If this turns out to be false in the future, we can add a HW flag.

wifi: cfg80211/mac80211: Add support to get radio index

2025-06-24T13:19:27+00:00

Currently, per-radio attributes are set on per-phy basis, i.e., all the radios present in a wiphy will take attributes values sent from user. But each radio in a wiphy can get different values from userspace based on its requirement. To extend support to set per-radio attributes, add support to get radio index from userspace. Add an NL attribute - NL80211_ATTR_WIPHY_RADIO_INDEX, to get user specified radio index for which attributes should be changed. Pass this to individual drivers, so that the drivers can use this radio index to change per-radio attributes when necessary. Currently, per-radio attributes identified 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 By default, the radio index is set to -1. This means the attribute should be treated as a global configuration. If the user has not specified any index, then the radio index passed to individual drivers would be -1. This would indicate that the attribute applies to all radios in that wiphy.

wifi: mac80211: add link_sta_statistics ops to fill link station statistics

2025-06-24T13:19:27+00:00

Currently, link station statistics for MLO are filled by mac80211. But there are some statistics that kept by mac80211 might not be accurate, so let the driver pre-fill the link statistics. The driver can fill the values (indicating which field is filled, by setting the filled bitmapin in link_station structure). Statistics that driver don't fill are filled by mac80211. Hence, add link_sta_statistics callback to fill link station statistics for MLO in sta_set_link_sinfo() by drivers.

wifi: mac80211: set ieee80211_prep_tx_info::link_id upon Auth Rx

2025-02-11T10:59:07+00:00

This will be used by the low level driver. Note that link_id will be 0 in case of a non-MLO authentication. Also fix a call-site of mgd_prepare_tx() where the link_id was not populated. Update the documentation to reflect the current state ieee80211_prep_tx_info::link_id is also available in mgd_complete_tx().

wifi: mac80211: don't flush non-uploaded STAs

2025-01-13T14:34:09+00:00

If STA state is pre-moved to AUTHORIZED (such as in IBSS scenarios) and insertion fails, the station is freed. In this case, the driver never knew about the station, so trying to flush it is unexpected and may crash. Check if the sta was uploaded to the driver before and fix this.

wifi: mac80211: get tx power per link

2024-12-04T15:17:40+00:00

ML interfaces can have multiple affiliated links to it and hence there is a need to report tx power of specified link rather deflink. Add changes to report tx power of requested link from mac80211, also pass link id as an argument in get_tx_power op so that supported drivers can use it to report link's tx power.

wifi: mac80211: call rate_control_rate_update() for link STA

2024-10-23T14:43:27+00:00

In order to update the right link information, call the update rate_control_rate_update() with the right link_sta, and then pass that through to the driver's sta_rc_update() method. The software rate control still doesn't support it, but that'll be skipped by not having a rate control ref. Since it now operates on a link sta, rename the driver method.
