In ACPI SAR enabled device, mt7921 should read power limit in ACPI config. The limit value would be applied to regular tx power settings in mt76. Two major functionalities added: 1. Get SAR power table through ACPI. 2. Read power in Dynamic/Geo SAR table for tx power limit.

A pending packet uses a cookie as an unique key, but it can be duplicated because it didn't use atomic operators. And also, a pending packet can be null in hwsim_tx_info_frame_received_nl due to race condition with mac80211_hwsim_stop. For this, * Use an atomic type and operator for a cookie * Add a lock around the loop for pending packets Signed-off-by:

commit dd374f84 ("wifi: nl80211: expose link ID for associated BSSes") used a top-level attribute to send link ID of the associated BSS in the nested attribute NL80211_ATTR_BSS. But since NL80211_ATTR_BSS is a nested attribute of the attributes defined in enum nl80211_bss, define a new attribute in enum nl80211_bss and use it for sending the link ID of the BSS.

Increase akm_suites array size in struct cfg80211_crypto_settings to 10 and advertise the capability to userspace. This allows userspace to send more than two AKMs to driver in netlink commands such as NL80211_CMD_CONNECT. This capability is needed for implementing WPA3-Personal transition mode correctly with any driver that handles roaming internally. Currently, the possible AKMs for multi-AKM connect can include PSK, PSK-SHA-256, SAE, FT-PSK and FT-SAE. Since the count is already 5, increasing the akm_suites array size to 10 should be reasonable for future usecases. Signed-off-by:

The current check only worked for AP mode, but we can do radar detection in mesh as well (for example). We could try to check this using wdev_chandef(), but we also don't really care since the chandef is passed in and we have no need to use it anymore (since we added the argument in commit d2859df5 ("cfg80211/mac80211: DFS setup chandef for cac event")).

In many cases we might get here from driver code that's not really set up to care about the locking, and for the non-MLO cases we really don't care so much about it. So relax the checking here for now, perhaps we should even remove it completely since we might not really care if we point to an invalid link's chandef and can require the caller to check the link validity first.

When a client does not generate any local tx activity, accumulating airtime deficit for the round-robin scheduler can be harmful. If this goes on for too long, the deficit could grow quite large, which might cause unreasonable initial latency once the client becomes active Signed-off-by:

Felix Fietkau authored
In order to maintain fairness, the amount of queueing needs to be limited beyond the simple per-station AQL budget, otherwise the driver can simply repeatedly do scheduling rounds until all queues that have not used their AQL budget become eligble. To be conservative, use the high AQL limit for the first txq and add half of the low AQL for each subsequent queue. Signed-off-by:

This allows proper deficit accounting to ensure that they don't carry their deficit until the next time they become active Signed-off-by:
-
Felix Fietkau authored
When queueing packets for a station, deficit only gets added once the packets have been transmitted, which could be much later. During that time, a lot of temporary unfairness could happen, which could lead to bursty behavior. Fix this by subtracting the aql_tx_pending when checking the deficit in tx scheduling.
