2020-12-04mt76: mt7915: introduce dbdc supportLorenzo Bianconi
Introduce mt7915 dbdc support. If dbdc is available, mt7915 primary phy will work on 2.4GHz band, while secondary one on 5GHz band.

2020-12-04mt76: mt7915: use BIT_ULL for omac_idxRyder Lee
The omac_idx variable is u64 so we should use the 64-bit BIT_ULL(). Signed-off-by: Ryder Lee <ryder.lee@mediatek.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-12-04mt76: mt7915: implement testmode tx supportShayne Chen

2020-12-04mt76: switch to wep sw crypto for mt7615/mt7915Lorenzo Bianconi
Switch to wep sw crypto for mt7615/mt7915 since wtbl require a sta reference and wep key is not pairwise Tested-by: YN Chen <yn.chen@mediatek.com> Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-12-04mt76: mt7915: query station rx rate from firmwareFelix Fietkau
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. Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-12-04mt76: mt7915: support 32 station interfacesFelix Fietkau
When looking for a MAC address slot, start by using main BSSID slots 1-3, afterwards use 16 repeater mode BSSID slots, then start using the slots usually used for AP mode. This search order should prevent unnecessary conflicts with AP mode interfaces on the same PHY Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-12-04mt76: mt7915: add encap offload for 4-address mode stationsFelix Fietkau

2020-09-24mt76: remove retry_q from struct mt76_txq and related codeFelix Fietkau
Since the switch to using AQL by default, mtxq->retry_q is never filled anymore Remove it to get rid of a few more unnecessary cycles in the tx path Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-09-24mt76: mt7915: simplify aggregation session checkFelix Fietkau
Use the txwi data as primary source information to avoid touching skb data Use bitfield instead of state variable + spinlock Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-09-24mt76: mt7915: enable offloading of sequence number assignmentFelix Fietkau
Preparation for supporting more offload features Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-09-24mt76: mt7915: clean up station stats polling and rate control updateFelix Fietkau
Queueing a per-sta work item from the tx free path can become very expensive under load. This work is only supposed to pull rate control stats every second and deal with rate control changes. Additionally, the rate control update code was wrong, because it was confusing bit masks and bit numbers in test_bit. Fix this by introducing a dedicated device work item for rate control updates, and by polling station stats from the phy mac work. Stations requiring polling or rate control updates are added to lists protected by dev->sta_poll_lock. Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-07-21mt76: vif_mask to struct mt76_phyFelix Fietkau
All drivers use this in pretty much the same way. Moving it to core helps with some checks for the upcoming testmode support Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-07-21mt76: mt7915: use ieee80211_tx_queue_params to avoid open codedRyder Lee

2020-07-21mt76: mt7915: add a fixed AC queue mappingRyder Lee
In MT7915, hardware queue map is flexible. However, certain firmware modules like MU and U-APSD presume a fixed queue order to adapt some devices that have DMA scheduler with a strict order, so this patch can help in the long run.

2020-07-21mt76: add missing lock configuring coverage classLorenzo Bianconi
