Subject: [PATCH v5 0/6] ath11k: add monitor mode support
Date: Mon, 15 Apr 2019 17:12:50 -0700	[thread overview]
Message-ID: <1555373576-4771-1-git-send-email-milehu@codeaurora.org> (raw)

Adding monitor mode in ath11k. It can be enabled
 by commands below:

  ifconfig wlan0 down
  iw wlan0 set type monitor
  ifconfig wlan0 up

change channel:
  iw wlan0 set freq 5805 80 5775

Change summary:
1. create monitor status/destination/buffer/link descriptor rings.
2. enable these rings and push ring filters to buffer/status rings.
3. add napi entry point for monitor status and destination rings process.
4. implement monitor status/buffer rings replenish.
5. process entries from the status ring to get ppdu id and tlv status.
6. process entries from the destination ring by comparing ppdu id to build
    msdu list.
7. merge msdu list to mpdu and copy rx status to cb.
8. deliver mpdu to upper layer.

Known issues:
 - Coexist with other interface type (AP/STA) not fully supported.
 - higher data rates (11ax) not supported. radiotap needs proper info.
 - signal strength and rate idx not accurate in some packets.

  ath11k: init/deinit monitor rings
  ath11k: monitor filter set function
  ath11k: htt setup monitor rings
  ath11k: monitor mode attach/detach
  ath11k: enable/disable monitor mode and destination ring entry process
  ath11k: merge msdu tlv process and status/destination ring process

V2:
 - correct wrong indent and style.
 - change function return value to bool.
 - remove redundent code.
 - correct warn message style and remove __func__ and __LINE__.
 - remove likely and unlikely functions.

V3:
 - create common ring reap function for peer-stats and monitor mode.

V4:
 - change bool to atomic_t to add protection
 - remove unnecessary print

V5:
 - replace atomic_t by atomic bitmask
