[v3,0/8] wifi: cfg80211/mac80211: add DFS support for MLO

Message

Aditya Kumar Singh July 11, 2024, 3:51 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.

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
