[v6,0/8] wifi: cfg80211/mac80211: add DFS support for MLO

Message

Aditya Kumar Singh Sept. 6, 2024, 6:44 a.m. UTC

Currently, Dynamic Frequency Selection (DFS) and its related radar events
are supported only for non-MLO case where deflink (or link_id 0) is always
considered. However, with MLO in place, there is need to handle DFS in
per-link manner instead of always handling it on per device.

Add support to handle DFS interference related events per-link basis.

  wifi: mac80211: remove label usage in
    ieee80211_start_radar_detection()
  wifi: trace: unlink rdev_end_cac trace event from wiphy_netdev_evt
    class
  wifi: cfg80211: move DFS related members to links[] in wireless_dev
  wifi: cfg80211: handle DFS per link
  wifi: mac80211: handle DFS per link
  wifi: cfg80211/mac80211: use proper link ID for DFS
  wifi: mac80211: handle ieee80211_radar_detected() for MLO

v6: * Rebased on ToT
    * No changes in 1-5 and 7.
    * used link instead of link_data in 6.
    * Used link to get conf.
    * Removed unnecessary typecast in patch 8 function
      ieee80211_radar_mark_chan_ctx_iterator().

v5: * No changes in 1-7.
    * Fixed sparse warning in 8.

v4: * Rebased on ToT
    * No other changes in [1-7]
    * Removed local linked list usage and refactored code to directly
      cancel and notify while iterating over radar detected channel
      context [8]

v3: * Rebased on ToT
    * 12-digit sha1 in [1/8]
    * moved trivial preparation patches on top.
    * changed radar detection handling logic in [8/8]
    * minor commit text changes in in [5/8], [6/8]
    * removed patch [v2 9/9]

v2: * No changes except patch [6/9].
    * In [6/9], removed usage of label and directly used return statements
