    iwlwifi: mvm: support mac80211 TXQs model · cfbc6c4c
    Sara Sharon authored
    Move to use the new mac80211 TXQs implementation. This has
    quite a few benefits for us. We can get rid of the awkward
    mapping of DQA to mac80211 queues. We can stop buffering
    traffic while waiting for the queue to be allocated. We can
    also use mac80211 AMSDUs instead of building it ourselves.
    
    The usage is pretty simple:
    Each ieee80211_txq contains iwl_mvm_txq. There is such a
    queue for each TID, and one for management frames. We keep
    having static AP queues for probes and non-bufferable MMPDUs,
    along with broadcast and multicast queues. Those are being
    used from the "old" TX invocation path - iwl_mvm_mac_tx.
    
    When there is a new frame in a TXQ, iwl_mvm_mac_wake_tx is
    being called, and either invokes the TX path, or allocates
    the queue if it does not exist.
    
    Most of the TX path is left untouched, although we can consider
    cleaning it up some more, for example get rid of the duplication
    of txq_id in both iwl_mvm_txq and iwl_mvm_dqa_txq_info.
