Mac80211 core may ask driver to change to idle mode during HW scan, then H2C command for HW scan will send failed since chip is in idle mode. Therefore, We check the SCANNING flag before entering IPS to prevent this behavior. Signed-off-by:

When Wi-Fi & Bluetooth are both busy at the same time, Wi-Fi need to enable RX gain to protect Wi-Fi RX RF ability. Without this configure the interference from Bluetooth will bring a big impact to Wi-Fi RX. Signed-off-by:

In WoWLAN Mode, it's expected that WiFi chip could enter power save mode only after all setting is finished, but current wow_enter_lps function break the rule and may lead to WoWLAN function fail in low probability, so fix it. Signed-off-by:

To support WoWLAN mode for 8852be, we add one PLE quota setting and WoWLAN stub, which shows that supported WLAN events include receiving magic packet, rekey packet and deauth packet, and disconnecting from AP. Signed-off-by:

Since we didn't reset t to 0, only the first iteration of the loop did checked the ready bit several times. From the second iteration and on, we just tested the bit once and continued to the next iteration. Reported-and-tested-by:

Newer firmware images have a TLV advertising how many beacons they support, use that to permit adding more links in AP mode (FW needs to support at least as many links as beacons). Signed-off-by:

Implement switching keys from one set of firmware station IDs to another set, during link switch. Signed-off-by:
-
Johannes Berg authored
When we switch station links, also add the code to switch BAIDs from one station mask to the new one. To do so, refactor the switching code a bit to have common code for all the needed switches; will add keys next. Signed-off-by:

Johannes Berg authored
When we have MLO connections, a BAID applies to multiple firmware stations. Track the station mask instead of the station ID, getting rid of a few more deflink cases and preparing for handling link switching for BAIDs. Signed-off-by:

When we remove a queue we need to use the currently active firmware stations in the mask, not the deflink one. Fix that. Signed-off-by:

The initiator smooth list is initialized only in iwl_mvm_up(), but is cleared in iwl_mvm_mac_stop. This may result in iterating over the list before it was initialized in case iwl_mvm_up() failed early. Fix it by moving the list initialization to an earlier stage.

We are going to need this in more places than just the key code, so factor out the functionality of getting the FW station ID mask (filtered to a specific link if needed) to a separate function that can now be called both under RCU and mvm->mutex protection. Signed-off-by:

The firmware split the HE support field into HE and "pseudo HE", the latter is really for AP and doesn't implement trigger frame handling for example. Use the new field for AP mode. Signed-off-by:

The usage of the 'dtim_period' value was wrong, as it is only a multiplier of the beacon interval, and thus, beacon interval should also be considered. Fix it. Signed-off-by:

In iwl_mvm_mac_ctxt_get_lowest_rate() we were still accessing vif->bss_conf without any multi-link provisions, and also the info->band, both of which isn't valid in MLO. Fix the code to look at the correct link. In case of EAPOL transmissions for the initial 4-way-HS, look up the correct link here as well, and warn if multiple are active. Signed-off-by:

Add SDIO ids for use with the muRata 1YN (Cypress CYW43439). The odd thing about this is that the previous 1YN populated on M.2 card for evaluation purposes had BRCM SDIO vendor ID, while the chip populated on real hardware has a Cypress one. The device ID also differs between the two devices. But they are both 43439 otherwise, so add the IDs for both. On-device 1YN (43439), the new one, chip label reads "1YN": ``` /sys/.../mmc_host/mmc2/mmc2:0001 # cat vendor device 0x04b4 0xbd3d ``` EA M.2 evaluation board 1YN (43439), the old one, chip label reads "1YN ES1.4": ``` /sys/.../mmc_host/mmc0/mmc0:0001/# cat vendor device 0x02d0 0xa9a6 ``` Reviewed-by:
