2019-01-25iwlwifi: mvm: support mac80211 TXQs modelSara Sharon9-443/+331
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.

2019-01-25iwlwifi: mvm: make NVM access actually fail on failuresJohannes Berg1-3/+7
On any failure, including if we crash the firmware or get garbage data, we currently ignore this and pretend the OTP was empty. Clearly, this isn't typically the case. In cases other than the firmware saying it can't read the requested section, or the section having ended, make the access actually fail and trickle the error up through the layers to fail init.

2018-12-20iwlwifi: mvm: d3: use struct_size() in kzalloc()Gustavo A. R. Silva1-4/+2
One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct foo { int stuff; void *entry[]; }; instance = kzalloc(sizeof(struct foo) + sizeof(void *) * count, GFP_KERNEL); Instead of leaving these open-coded and prone to type mistakes, we can now use the new struct_size() helper: instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL); This issue was detected with the help of Coccinelle.

Sometimes, due to SCD bug, we need to start the queue with an higher SSN.
