2023-11-20wifi: mt76: mt7921: fix the wrong rate pickup for the chanctx driverSean Wang1-2/+7
[ Upstream commit 32b1000db221df33ec8b57794a091ba6075b6c28 ] The variable band should be determined by the ieee80211_chanctx_conf when the driver is a kind of chanctx one e.g mt7921 and mt7922 driver so we added the extension to mt76_connac2_mac_tx_rate_val by distinguishing if it can support chanctx to fix the incorrect rate pickup.

2023-08-07page_pool: split types and declarations from page_pool.hYunsheng Lin1-1/+0
Split types and pure function declarations from page_pool.h and add them in page_page/types.h, so that C sources can include page_pool.h and headers should generally only include page_pool/types.h as suggested by jakub. Rename page_pool.h to page_pool/helpers.h to have both in one place.

Trying to probe a mt7921e pci card without firmware results in a successful probe where ieee80211_register_hw hasn't been called. When removing the driver, ieee802111_unregister_hw is called unconditionally leading to a kernel NULL pointer dereference. Fix the issue running mt76_unregister_device routine just for registered hw.

2022-02-24mt76: fix dfs state issue with 160 MHz channelsFelix Fietkau1-1/+1
When operating on a mix of DFS and non-DFS channels, the driver only checks the CAC status of the control channel. This causes beacons/tx to fail if the control channel is on a non-DFS channel. Fix this by calling cfg80211_reg_can_beacon to determine the DFS status of all affected channels Signed-off-by: Felix Fietkau <nbd@nbd.name>
2022-02-24mt76: improve signal strength reportingFelix Fietkau1-0/+32
Instead of just taking the maximum per-chain signal strength values, add an approximation for the sum of the combined signal. This should more accurately reflect the real signal strength, especially if the per-chain signal strength values are close to each other Signed-off-by: Felix Fietkau <nbd@nbd.name>
2022-02-03mt76: mt7915: fix/rewrite the dfs state handling logicFelix Fietkau1-0/+28
Client mode on DFS channels was broken, because the old code was activating the DFS detector on radar channels while leaving it in CAC state. This was caused by making the decision based on the channel radar flag, instead of hw->conf.radar_enabled. In order to properly deal with the various corner cases, rip out the state handling code and replace it with something that's much easier to reason about.

2021-12-19mt76: clear sta powersave flag after notifying driverFelix Fietkau1-2/+4
If the driver has configured the hardware to drop packets for a sta that was in powersave mode, then clearing the flag too early opens up a small race window during which packets could be dropped on wakeup Signed-off-by: Felix Fietkau <nbd@nbd.name>

2021-10-20mt76: use a separate CCMP PN receive counter for management framesXing Song1-4/+23
When received frame is decryped by hardware, CCMP PN is checked by mt76. When management frame protection (IEEE 802.11w) is used, we must use a separate counter for tracking received CCMP packet number for the management frames. The previously used counter was shared with data frames and that can cause problems in detecting replays incorrectly for robust management frames. Add a new counter just for robust management frames to avoid this issue. Signed-off-by: Xing Song <xing.song@mediatek.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>
