2022-06-06ath11k: fix missing skb drop on htc_tx_completion errorChristian 'Ansuel' Marangi
On htc_tx_completion error the skb is not dropped. This is wrong since the completion_handler logic expect the skb to be consumed anyway even when an error is triggered. Not freeing the skb on error is a memory leak since the skb won't be freed anywere else. Correctly free the packet on eid >= ATH11K_HTC_EP_COUNT before returning.

2022-03-18ath11k: Add basic WoW functionalitiesCarl Huang
Implement basic WoW functionalities such as magic-packet, disconnect and pattern. The logic is very similar to ath10k. When WoW is configured, ath11k_core_suspend and ath11k_core_resume are skipped as WoW configuration and hif suspend/resume are done in ath11k_wow_op_suspend() and ath11k_wow_op_resume().

2021-11-17ath11k: Disabling credit flow for WMI pathP Praneesh
Firmware credit flow control is enabled for WMI control services, which expects available tokens should be acquired before sending a command to the target. Also the token gets released when firmware receives the command. This credit-based flow limits driver to send WMI command only when the token available which is causing WMI commands to timeout and return -EAGAIN, whereas firmware has enough capability to process the WMI command. To fix this Tx starvation issue, introduce the ability to disable the credit flow for the WMI path. The driver sends WMI configuration for disabling credit flow to firmware by two ways. 1. By using a global flag (HTC_MSG_SETUP_COMPLETE_EX_ID msg type flags) 2. By using a local flag (ATH11K_HTC_CONN_FLAGS_DISABLE_CREDIT_FLOW_CTRL = 1 << 3) Ath11k uses both these configurations to disable credit flow for the WMI path completely. Also added a hw_param member for credit flow control by which we can enable or disable it based on per-target basis. Currently we are disabling credit flow for IPQ8074, IPQ6018, and QCN9074 as recommended by firmware.

2020-12-12ath11k: set credit_update flag for flow controlled ep onlyCarl Huang
Firmware will check all the pipes before entering WoW mode during suspend. If ATH11K_HTC_FLAG_NEED_CREDIT_UPDATE is set, firmware treats this pipe needed to return credit even though it's actually not required. If any pipe needs to return credit, the suspend_complete message doesn't send to host but is dropped. So host gets time out and WoW suspend failed.

2019-11-25ath11k: driver for Qualcomm IEEE 802.11ax devicesKalle Valo
ath11k is a new driver for Qualcomm IEEE 802.11ax devices, first supporting only IPQ8074 SoC using the shared memory AHB bus. ath11k uses mac80211 and supports AP, Station and Mesh modes. Even though ath11k has some similar code as with ath10k (especially the WMI layer) it was concluded to be simpler to have a "clean start" for ath11k code base and not try to share the code with ath10k. This makes maintenance easier and avoids major changes in ath10k, which would have significantly increased the risk of regressions in existing setups. Even though the driver is very similar with ath10k but there are major differences as well. The datapath is completely different. ath11k supports multiple MACs, called "soc" in the firmware interface. And there's only one WMI interface to support. Currently ath11k supports only IEEE 802.11ac mode, but patches for 802.11ax are available and they will be submitted after ath11k is accepted to upstream. The firmware images are available from ath11k-firmware repository but they will be also submitted to linux-firmware: https://github.com/kvalo/ath11k-firmware This was tested with firmware version WLAN.HK.2.1.0.1-00629-QCAHKSWPL_SILICONZ-1.
