Merge mt76x0 and mt76x0 sta add/remove callback. We drop mt76x0_mac_set_ampdu_factor() for now.

2018-09-17mt76x0: fix remove_interfaceStanislaw Gruszka1-2/+1
We wrongly use wcid_mask instead of vif_mask. This creates problems when the interface is removed more than 8 times, for example with iw: iw dev <devname> interface add <name> type <type> iw dev <name> del This caused 'ifconfig up' to fail with error: SIOCSIFFLAGS: No space left on device Fixes: 95e444098a7b ("mt76x0: main file") Reported-and-tested-by: Sid Hayn <sidhayn@gmail.com> Signed-off-by: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

2018-09-06ath10k: wmi: disable softirq's while calling ieee80211_rxErik Stromdahl1-1/+2
This is done in order not to trig the below warning in ieee80211_rx_napi: WARN_ON_ONCE(softirq_count() == 0); ieee80211_rx_napi requires that softirq's are disabled during execution. The High latency bus drivers (SDIO and USB) sometimes call the wmi ep_rx_complete callback from non softirq context, resulting in a trigger of the above warning. Calling ieee80211_rx_ni with softirq's already disabled (e.g., from softirq context) should be safe as the local_bh_disable and local_bh_enable functions (called from ieee80211_rx_ni) are fully reentrant.

2018-09-06ath10k: htt: High latency RX supportErik Stromdahl3-3/+187
Special HTT RX handling for high latency interfaces. Since no DMA physical addresses are used in the RX ring config message (this is not supported by the high latency devices), no RX ring is allocated. All RX skb's are allocated by the driver and passed directly to mac80211 in the HTT RX indication handler. A nice side effect of this is that no huge buffer will be allocated with dma_alloc_coherent. On embedded systems with limited memory resources, the allocation of the RX ring is prone to fail. Some tweaks made to "make it work": Removal of protected bit in 802.11 header frame control field. The chipset seems to do hw decryption but the frame_control protected bit is still set. This is necessary for mac80211 not to drop the frame.

2018-09-06ath10k: htt: High latency TX supportErik Stromdahl1-0/+92
Add HTT TX function for HL interfaces. Intended for SDIO and USB. Signed-off-by: Erik Stromdahl <erik.stromdahl@gmail.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2018-09-06ath10k: htt: RX ring config HL supportErik Stromdahl1-0/+52
Special HTT RX ring config message used by high latency devices. The main difference between HL and LL is that HL devices do not use shared memory between device and host and thus, no host paddr's are added to the RX config message.

2018-09-06ath10k: DMA related fixes for high latency devicesErik Stromdahl3-9/+16
Several DMA related functions (such as the dma_map_xxx functions) are not used with high latency devices and don't need to be invoked in this case. Signed-off-by: Erik Stromdahl <erik.stromdahl@gmail.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2018-09-06ath10k: add per target config of max_num_peersErik Stromdahl1-5/+12
This patch makes sure the value of max_num_peers matches num_peers in hw_params (if set to a non zero value). hw_params->num_peers is used in the TLV WMI init command. If ar->max_num_peers is not set to the same value, there is a risk that the user creates more peers than the maximum number of peers supported by the device.

2018-09-06ath10k: use hw_params.num_peers for num_tids in TLV initErik Stromdahl1-1/+4
As TARGET_TLV_NUM_TIDS is calculated like this: #define TARGET_TLV_NUM_TIDS ((TARGET_TLV_NUM_PEERS) * 2) ... it is better to use the per device hw_params.num_peers value in the TLV init message (if set), rather than using a hard coded value. This makes the value used in the TLV init message match the hw_param value. Signed-off-by: Erik Stromdahl <erik.stromdahl@gmail.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2018-09-06ath10k: add bus type check in ath10k_init_hw_paramsErik Stromdahl3-9/+24
The bus type is used together with the other hw parameters to find a matching entry in ath10k_hw_params_list for the device. This is necessary since HL devices can have the same dev_id and target_version as a corresponding LL device (same chipset) and yet use a totally different configuration.

2018-09-06ath10k: add device type enum to ath10k_bus_paramsErik Stromdahl7-0/+13
Add dev_type parameter to struct ath10k_bus_params. The dev type specifies if the device is a high latency device (usb and sdio) or low latency device (pci, ahb and snoc) The setup of high latency chips is sometimes different than for chips using low latency interfaces.
