Currently, enum ieee80211_bss_change has more than 32 flags. Change the type of the corresponding variables from u32 to u64. Signed-off-by:

When we flush stations, we first take them off the list and then destroy them one by one. If we do the different mode recalculations while destroying them, we cause the following scenario: - STA 1 has 80 MHz - min chanctx width is now 80 MHz - STA 2 has 80 MHz - empty STA list - destroy STA 2 - recalc min chanctx width -> results in 20 MHz as the STA list is already empty This is broken, since as far as the driver is concerned STA 1 still exists at this point, and this causes issues at least with iwlwifi. Fix - and also optimize - this by doing the recalc of min chanctx width (and also P2P PS) only after all the stations were removed. Signed-off-by:

To fix a sequencing issue, this code needs to be changed a bit. Move it up in the file to prepare for that. Signed-off-by:

When adding a new link to a station, this needs to cause a recalculation of the minimum chandef since otherwise we can have a higher bandwidth station connected on that link than the link is operating at. Do the appropriate recalc. Fixes: cb71f1d1 ("wifi: mac80211: add sta link addition/removal") Signed-off-by:

The size of enum ieee80211_bss_change is bigger that 32, so we need u64 to be used in a flag. Also pass u64 instead of u32 to ieee80211_reconfig_ap_links() for the same reason. Signed-off-by:

Previously, I didn't implement restarting here at all if the interface is an MLD, so it only worked for non-MLO. Add the needed code to restart an AP MLD correctly. Signed-off-by:

If the station disables all links it's in powersave and we shouldn't transmit anything to it, but we don't handle that correctly yet. For now, just avoid the warning, once we really add support for this case we can revert to the old warning. Signed-off-by:

This isn't used, and there isn't really a good way it could be used, so just remove that. Signed-off-by: -

When PNVM is obtained from UEFI, there's an additional memory descriptor TLV that has to be handled. It is the same TLV that holds data in the reduced power tables. Also, in this TLV, the actual data is located after address and size, so add the corresponding offset. Signed-off-by:

Replace the field reduce_power_dram with a struct that holds data about the reduced-power tables drams regions. Generalize load_payloads_segments() to work for both pnvm tables and reduction power tables. Make required adjustments in the data structures. Signed-off-by:

Generalize the parsing, loading, and setting of the power-reduce tables, in order to support allocation of several DRAM payloads in the future. Signed-off-by:

Take the part that copies the tables into DRAM, out of the method that sets the prph_scratch to make the code cleaner. Each of the operations will get more complex in the future when it will also support larger power-reduce tables images. Signed-off-by:

Save the pnvm payloads in several DRAM segments (not only in one as used to). In addition, allocate a FW structure in DRAM that holds the segments' addresses and forward its address to the FW. It's done when FW has the capability to handle pnvm images this way (helps to process large pnvm images). Signed-off-by:

Change iwl_pnvm_parse so it will only save the information into the iwl_pnvm_image struct. This enables to use the parsing code for the power reduce tables in the future. Signed-off-by:

Take the part that is copying the pnvm image into DRAM, out of the the method that sets the prph_scratch. Makes the code cleaner since those 2 operations don't always happen together (loading should happen only once while setting can happen more than once). In addition, each operation will get more complex in the future when it will support also larger pnvm images. Signed-off-by:

Generalize iwl_pnvm_parse(). This saves us from copying each payload twice (first in the parsing and later when copying it to the dram). Moreover, its more compatible for handling larger pnvm tables in the future (in which payloads won't be concatenated). The main changes are: 1. Take out the concatenating of the payloads from the parsing level 2. Start using iwl_pnvm_image structure that will hold pointers to payloads that should be delivered to fw, their sizes and number.

Indicate to the firmware for each station whether or not MFP is used with this station. Note that we indicate MFP for it before authorized since we don't know yet, and that will make the firmware not handle should-be-protected management frames without being able to check them. Signed-off-by:

This warning is sometimes happening if we force a FW error while disconnecting, which is annoying but harmless. However, it's also pointless to throw a warning here, since the stack and driver state doesn't really help, so just remove that so the driver will ignore the error if any. Signed-off-by:

There are mainly two types of BTM (BSS Transition Management) requests, recommendations and notifications. For the first type, a response is needed otherwise, most probably the STA will be disconnected. Since we don't want to wake up the host on it, set the BTM to reject offload flag (if the device supports it) and rely on the FW to take care of it. The FW will reject the BTM request and in case the AP sends DEAUTH the FW can wake up the host to let it decide on the next steps. Signed-off-by:

DRAM buffers that are not defined in the TLVs (or are unused in the preset) would cause a log message. To avoid confusion, skip processing buffers with an invalid (i.e. uninitialized) DRAM path. This further reduces the noise of the message in cases where it is unlikely to be helpful. Also update a related debug log string to better describe what is happening. Signed-off-by:
