      iwlwifi: mvm: set the encryption type of an IGTK key · aa950524
      Ayala Beker 提交于
      The FW expect the driver to set the encryption algorithm type when
      installing the IGTK key in the HW.
      Currently when installing CMAC IGTK key we don't set the algorithm type
      and as a result the FW fails to calculate the MIC of multicast management
      frames.
      Fix it.

      iwlwifi: mvm: support dqa-mode agg on non-shared queue · cf961e16
      Liad Kaufman 提交于
      In non-shared queues, DQA requires re-configuring existing
      queues to become aggregated rather than allocating a new
      one. It also requires "un-aggregating" an existing queue
      when aggregations are turned off.
      
      Support this requirement for non-shared queues.

      iwlwifi: mvm: use helpers to get iwl_mvm_sta · 13303c0f
      Sara Sharon 提交于
      Getting the mvm station out of station id requires dereferencing
      the station id to get ieee80211_sta, then checking for pointer
      validity and only then extract mvm station out.
      Given that there are helpers to do it - use them instead of
      duplicating the code whenever we need only mvm station.

      iwlwifi: mvm: add reorder timeout per frame · 0690405f
      Sara Sharon 提交于
      Add a timer in order to release expired frames from the
      reorder buffer.
      This is needed since some APs do not retransmit frames
      to fill in the reorder holes and in TCP it results with
      a complete stall of traffic.
      
      This has a few side effects on the general design:
      
      The nssn may not reflect the the head of the reorder buffer.
      This situation is valid, and packets with SN lower than the
      reorder buffer head will be dropped.
      
      Another side effect is that since the reorder timer might expire
      we need to lock the reorder buffer.
      This however is fine since the locking is only inside a
      single reorder buffer between RX path and reorder timeout and
      there is no outside contention.

      iwlwifi: mvm: add reorder buffer per queue · b915c101
      Sara Sharon 提交于
      Next hardware will direct packets to core based on the TCP/UDP
      streams.
      This logic can create holes in reorder buffer since packets that
      belong to other stream were directed to a different core.
      However, those are valid holes and the packets can be indicated
      in L3 order.
      
      The hardware will utilize a mechanism of informing the driver of
      the normalized ssn and the driver shall release all packets that
      SN is lower than the nssn.
      This enables managing the reorder across the queues without sharing
      any data between them.
      
      The reorder buffer is allocated and released directly in the RX path
      in order to avoid various races between control path and rx path.
      The code utilizes the internal messaging to notify rx queues of when
      to delete the reorder buffer.

      iwlwifi: mvm: add infrastructure for tracking BA session in driver · 10b2b201
      Sara Sharon 提交于
      According to the spec when a BA session is started there
      is a timeout set for the session in the ADDBA request.
      If there is not activity on the TA/TID then the session
      expires and a DELBA is sent.
      In order to check for the timeout, data must be shared
      among the rx queues.
      Add a timer that runs as long as BA session is active
      for the station and stops aggregation session if needed.
      This patch also lays the infrastructure for the reordering
      buffer which will be enabled in the next patches.
