      cfg80211: clarify frames covered by average ACK signal report · 9c06602b
      Balaji Pothunoori authored
      Modify the API to include all ACK frames in average ACK
      signal strength reporting, not just ACKs for data frames.
      Make exposing the data conditional on implementing the
      extended feature flag.
      
      This is how it was really implemented in mac80211, update
      the code there to use the new defines and clean up some of
      the setting code.
      
      Keep nl80211.h source compatibility by keeping the old names.

      [rewrite commit log, change compatibility to be old=new
       instead of the other way around, update kernel-doc,
       roll in mac80211 changes, make mac80211 depend on valid
       bit instead of HW flag]

      mac80211: add missing WFA Multi-AP backhaul STA Rx requirement · 1ecef20c
      Sathishkumar Muruganandam authored
      The current mac80211 WDS (4-address mode) can be used to cover most of the
      Multi-AP requirements for Data frames per the WFA Multi-AP Specification v1.0.
      When configuring AP/STA interfaces in 4-address mode, they are able to function
      as fronthaul AP/backhaul STA of Multi-AP device complying below
      Tx, Rx requirements except one missing STA Rx requirement added by this patch.
      
      Multi-AP specification section 14.1 describes the following requirements:
      
      Transmitter requirements
      ------------------------
      1. Fronthaul AP
              i) When DA!=RA of backhaul STA, must use 4-address format
              ii) When DA==RA of backhaul STA, shall use either 3-address
                  or 4-address format with RA updated with STA MAC
      
                  (mac80211 support 4-address format via AP/VLAN interface)
      
      2. Backhaul STA
              i) When SA!=TA of backhaul STA, must use 4-address format
              ii) When SA==TA of backhaul STA, shall use either 3-address
                  or 4-address format with RA updated with AP MAC
      
                  (mac80211 support 4-address format via use_4addr)
      
      Receiver requirements
      ---------------------
      1. Fronthaul AP
              i) When SA!=TA of backhaul STA, must support receiving 4-address
                 format frames
              ii) When SA==TA of backhaul STA, must support receiving both
                  3-address and 4-address format frames
      
                  (mac80211 support both 3-addr & 4-addr via AP/VLAN interface)
      
      2. Backhaul STA
              i) When DA!=RA of backhaul STA, must support receiving 4-address
                 format frames
              ii) When DA==RA of backhaul STA,  must support receiving both
                  3-address and 4-address format frames
      
                  (mac80211 support only receiving 4-address format via
                   use_4addr)
      
      This patch addresses the above Rx requirement (ii) for backhaul STA to receive
      unicast (DA==RA) 3-address frames in addition to 4-address frames.
      
      The current design doesn't accept 3-address frames when configured in 4-address
      mode (use_4addr). Hence add a check to allow 3-address frames when DA==RA of
      backhaul STA (adhering to Table 9-26 of IEEE Std 802.11-2016).
      
      This case was tested with a bridged station interface when associated with
      a non-mac80211 based vendor AP implementation using 3-address frames for WDS.
      
      STA was able to support the Multi-AP Rx requirement when DA==RA. No issues,
      no loops seen when tested with mac80211 based AP as well.
      
      Verified and confirmed all other Tx and Rx requirements of AP and STA for
      Multi-AP respectively. They all work using the current mac80211-WDS design.
