2020-12-04mt76: mt7663s: fix a possible ple quota underflowLorenzo Bianconi1-1/+1
Properly account current consumed ple quota in mt7663s_tx_pick_quota routine and avoid possible underflow.

2020-12-04mt76: add back the SUPPORTS_REORDERING_BUFFER flagFelix Fietkau1-0/+1
It was accidentally dropped while adding multiple wiphy support Fixes fast-rx support and avoids handling reordering in both mac80211 and the driver Cc: stable@vger.kernel.org Fixes: c89d36254155 ("mt76: add function for allocating an extra wiphy") Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-12-04mt76: mt7915: query station rx rate from firmwareFelix Fietkau5-3/+127
When per-packet rate reporting is enabled, the hardware can get stuck under some conditions. It self-recovers quickly, but in practice this leads to reduced performance. In order to avoid running into this issue, disable per-packet rate reporting by default and query the rx rate from firmware instead, unless monitor mode is enabled.

2020-12-04mt76: mt7915: fix processing txfree eventsFelix Fietkau1-0/+1
In the MT7915 info, the fields for the WLAN index / queue overlap with the token id, and the MT_TX_FREE_PAIR bit indicates, which one is present. If MT_TX_FREE_PAIR is set, skip processing the token index, since the data will not be valid. This fixes accidentally freeing tokens which are still in use by the hardware with a wrong station pointer. Signed-off-by: Felix Fietkau <nbd@nbd.name>

This is primarily for testing and can be used in combination with monitor mode to make the card respond to packets sent to a specific MAC address. For now this is only exposed as a debug/testing feature, later on the approach might be used to support more concurrent station interfaces Signed-off-by: Felix Fietkau <nbd@nbd.name>

Added multiple queues[BK,BE,VI,VO] to handle different priority data packets. Before adding a packet to the queue, checked its priority from the header, and then add to the suitable queue.

2020-12-02rtw88: coex: add function to avoid cck lockChing-Te Ku4-34/+155
Some AP will not follow the power save request, or it cannot stop transmission until its queue is empty. It may bring the decreasing of data rate. WLAN firmware will count is the AP still leaked packet after power save handshake was done or not to enable WLAN slot extend mechanism. The extend WLAN slot mechanism will extend the WLAN slot after power save handshake, 5 ms per times, maximum is 5 times to received the leaked packet to avoid the rate lower down. And if the transmission was already locked at CCK rate. The extended WLAN slot can also increase the opportunity that we can received the CCK's long packet and be released from CCK rate. While BT multi-link status was finished, there is possible that it still has some packet remained for seconds. Add a timer to remain the multi-link mechanism to protect WLAN Rx.
