2018-07-30mt76x2: fix CCK protection control frame rateLorenzo Bianconi1-3/+9
Use 11M as tx rate for CCK protection control frames Fixes: 7bc04215a66b ("mt76: add driver code for MT76x2e") Signed-off-by: Lorenzo Bianconi <lorenzo.bianconi@redhat.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2018-05-23mt76: use udelay instead of usleep_range in mt76x2_mac_stopFelix Fietkau1-1/+1
usleep_range can cause excessive latency on channel change if waiting for the MAC to stop fails. It will be forced to stop by the code following that loop anyway. Signed-off-by: Felix Fietkau <nbd@nbd.name> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2018-05-23mt76: move ieee80211_hw allocation to common coreFelix Fietkau1-8/+6

2018-05-23mt76x2: apply coverage class on slot time tooLorenzo Bianconi1-0/+3
According to 802.11-2007 17.3.8.6 (slot time), the slot time should be increased by 3 us * coverage class. Taking into account coverage class in slot time configuration allows to increase by an order of magnitude the throughput on a 4Km link in a noisy environment Tested-by: Luca Bisti <luca.bisti@gmail.com> Tested-by: Gaetano Catalli <gaetano.catalli@gmail.com> Signed-off-by: Lorenzo Bianconi <lorenzo.bianconi@redhat.com> Acked-by: Felix Fietkau <nbd@nbd.name> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2018-05-12mt76x2: add a polling delay in mt76x2_mac_stop routineLorenzo Bianconi1-5/+5
Add a usleep_range in mt76x2_mac_stop routine in order to add a polling delay checking values of MT_MAC_STATUS and IBI_R12 registers Signed-off-by: Lorenzo Bianconi <lorenzo.bianconi@redhat.com> Acked-by: Felix Fietkau <nbd@nbd.name> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2018-04-30mt76: fix concurrent rx calls on A-MPDU releaseFelix Fietkau1-0/+1
Add a spinlock in mt76_rx_complete. Without this, multiple stats updates could happen in parallel, which can lead to deadlocks. There are probably more corner cases fixed by this change. Signed-off-by: Felix Fietkau <nbd@nbd.name> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2018-04-24mt76x2: make mt76x2_mac_reset routine staticLorenzo Bianconi1-1/+1
Add static qualifier to mt76x2_mac_reset routine and remove the prototype from mt76x2_mac.h since it is used just in mt76x2_init.c Signed-off-by: Lorenzo Bianconi <lorenzo.bianconi@redhat.com> Acked-by: Felix Fietkau <nbd@nbd.name> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2018-03-13mt76: initialize available_antennas_{tx,rx} infoLorenzo Bianconi1-0/+3
Initialize available_antennas related info in wiphy data structure according to antenna_mask field; antenna_mask info is initialized in device specific code and will be used in mac80211 {set,get}_antenna callbacks Signed-off-by: Lorenzo Bianconi <lorenzo.bianconi@redhat.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2018-02-01mt76: implement AP_LINK_PSFelix Fietkau1-0/+1
With software A-MPDU reordering in place, frames that notify mac80211 of powersave changes are reordered as well, which can cause connection stalls. Fix this by implementing powersave state processing in the driver. Fixes: aee5b8cf2477 ("mt76: implement A-MPDU rx reordering in the driver code") Signed-off-by: Felix Fietkau <nbd@nbd.name> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2018-01-26mt76: validate rx CCMP PNFelix Fietkau1-1/+1
Apparently hardware does not perform CCMP PN validation in hardware, so we need to take care of this in the driver. This is important for protecting against replay attacks. Since validation of fragmented frames is more complex, the CCMP header for those is preserved. To keep the counter in sync, the first fragment is verified by both mt76 and mac80211, and all other fragments only by mac80211.

2018-01-26mt76: implement A-MPDU rx reordering in the driver codeFelix Fietkau1-0/+2

2018-01-24mt76x2: init: disable all pending tasklets during device removalLorenzo Bianconi1-0/+2
There is a possible race in mt76x2_stop_hardware() since pre_tbtt and dfs tasklets could run during driver cleanup. Fix it disabling all pending tasklets during device removal Signed-off-by: Lorenzo Bianconi <lorenzo.bianconi@redhat.com> Acked-by: Felix Fietkau <nbd@nbd.name> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2018-01-24mt76x2: dfs: add set_domain handlerLorenzo Bianconi1-1/+1

2018-01-08mt76x2: init: fix rx filter default value during initLorenzo Bianconi1-1/+2
mt76x2_mac_start writes dev->rxfilter to the hardware. It also happens during init, before dev->rxfilter is filled with the initval register value, leading to issues like promisc mode being enabled unconditionally. Fix this by reading the default value into dev->rxfilter earlier Signed-off-by: Lorenzo Bianconi <lorenzo.bianconi83@gmail.com> Signed-off-by: Felix Fietkau <nbd@nbd.name> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

2018-01-08mt76x2: convert between per-chain tx power and combined outputFelix Fietkau1-0/+3
Using both chains adds max. 3 dBm. A similar worst-case calculation is being used in ath9k as well to ensure that the hardware stays within regulatory limits Signed-off-by: Felix Fietkau <nbd@nbd.name> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2018-01-08mt76x2: initialize channel power limits at probe timeFelix Fietkau1-0/+30

2017-12-07mt76: add driver code for MT76x2eFelix Fietkau1-0/+839
MT76x2e is a 2x2 PCIe 802.11ac chipset by MediaTek. This driver has full support for AP, station, ad-hoc, mesh and monitor mode. Signed-off-by: Felix Fietkau <nbd@nbd.name> Signed-off-by: Lorenzo Bianconi <lorenzo.bianconi83@gmail.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
