From: Emmanuel Grumbach Date: Thu, 4 Oct 2018 10:41:45 +0300 Subject: [PATCH 10/32] iwlwifi: mvm: fix firmware statistics usage The new (CDB) statistics API is used by non-CDB devices as well. Look at the right TLV flag to know which version of the statistics notification to use. To avoid confusion, remove the _cdb suffix from the structure name. While at it, remove a structure that was never used.

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.
