My previous patch "ath9k: fix tx99 with monitor mode interface" made it possible to set it up this way again. However, it was removing support for using an active monitor interface, which is required for controlling the bitrate as well, since the bitrate is not passed down with a regular monitor interface. This patch partially reverts the previous one, but keeps support for using a regular monitor interface to keep documented steps working in cases where the bitrate does not matter Fixes: d9c52fd17cb48 ("ath9k: fix tx99 with monitor mode interface") Signed-off-by: Felix Fietkau <nbd@nbd.name> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

Therefore, let's not make the magnitude check so strict so we can get those samples released to userspace.

With WMI_10_4_PEER_STA_PS_STATECHG_EVENTID event, ps state of each peer is reported to user space via debugfs. Use the below command to get the ps state of each sta: cat /sys/kernel/debug/ieee80211/phyX/netdev::wlanX/stations/ XX:XX:XX:XX:XX:XX/peer_ps_state If STA is in power save state, we get the peer_ps_state value as 1. if STA is not in power save state, we get the peer_ps_state value as 0. If ps_state event is disabled, we get the peer_ps_state value as 2. We can enable/disable the ps_state events using the debugfs flag "ps_state_enable" echo Y > /sys/kernel/debug/ieee80211/phyX/ath10k/ps_state_enable Y = 1 to enable and Y = 0 to disable Tested in QCA4019 with firmware ver 10.4-3.2.1.1-00011 Signed-off-by: Maharaja Kennadyrajan <mkenna@codeaurora.org> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

But when the user selects different basic rates from the userspace, we need to send the management packets at the lowest basic rate selected by the user. This change makes use of WMI_VDEV_PARAM_MGMT_RATE param for configuring the management packets rate to the firmware.

Currently, only high latency devices (USB and SDIO) need to use this value, since the value obtained from the WMI op version is not applicable for these devices. Many devices in ath10k_hw_params_list have the wrong value set. An example of this is the QCA9880 hw2.0 chipset that had (before this patch) num_peers set to TARGET_TLV_NUM_PEERS although the firmware uses WMI version ATH10K_FW_WMI_OP_VERSION_10_2_4. Using the wrong value for the QCA9880 chip results in a fw crash: ath10k_pci 0000:01:00.0: firmware crashed!

Along with this, we should admit that it's possible for system firmware to be screwed up as well, omitting the MAC address there. Provide a fallback, such that we choose a randomly-generated MAC address, with the local assignment bit set. This is not a preferred mode of operation and really should only serve the purpose of keeping the system chugging along while someone figures out what's wrong with the system. Grepping through other wireless drivers shows very similar fallback logic though, so why not? git grep eth_random_addr drivers/net/wireless/ Signed-off-by: Brian Norris <briannorris@chromium.org> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

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.

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.
