iwl_mvm_tcool_get_cur_state is the function that returns the cooling state index to the sysfs handler. This function returns mvm->cooling_dev.cur_state but that variable was set to the budget and not the cooling state index. Fix that. Add a missing blank line while at it.

We need to track the next packet that we will reclaim in order to know when the Tx queues are empty. This is useful when we open or tear down an A-MPDU session which requires to switch queue. The next packet being reclaimed is identified by its WiFi sequence number and this is relevant only when we use QoS. QoS NDPs do have a TID but have a meaningless sequence number. The spec mandates the receiver to ignore the sequence number in this case, allowing the transmitter to put any sequence number. Our implementation leaves it 0. When we reclaim a QoS NDP, we can't update the next_relcaim counter since the sequence number of the QoS NDP itself is invalid. We used to update the next_reclaim based on the sequence number of the QoS NDP which reset it to 1 (0 + 1) and because of this, we never knew when the queue got empty. This had to sad consequence to stuck the A-MPDU state machine in a transient state. To fix this, don't update next_reclaim when we reclaim a QoS NDP. Alesya saw this bug when testing u-APSD. Because the A-MPDU state machine was stuck in EMPTYING_DELBA, we updated mac80211 that we still have frames for that station when it got back to sleep. mac80211 then wrongly set the TIM bit in the beacon and requested to release non-existent frames from the A-MPDU queue. This led to a situation where the client was trying to poll frames but we had no frames to send.

From 9000 family on, we need to get HW address from host CSR registers. OEM can override it by fusing the override registers - read those first, and if those are 0 - read the OTP registers instead. In addition - bail out if no valid mac address is present. Make it shared for all NICs.

We kick the allocator when we have 2 RBDs that don't have attached RBs, and the allocator allocates 8 RBs meaning that it needs another 6 RBDs to attach the RBs to. The design is that allocator should always have enough RBDs to fulfill requests, so we give in advance 6 RBDs to the allocator so that when it is kicked, it gets additional 2 RBDs and has enough RBDs. These RBDs were taken from the Rx queue itself, meaning that each Rx queue didn't have the maximal number of RBDs, but MAX - 6. Change initial number of RBDs in the system to include both queue size and allocator reserves. Note the multi-queue is always 511 instead of 512 to avoid a full queue since we cannot detect this state easily enough in the 9000 arch.

Currently when the FW sends start/stop aux roc time event notification with an error status, the driver returns an error value, but does not remove the time event, and does not notify the stack above that the time event is over. This causes problems that the stack above assumes we are still in the middle of a time event, and therefore can block different events, such as scanning. On FW failure notification, cleanup the time event parameters and notify the stack above that the time event is over.

Before authentication, we start a time event during which we wait for a beacon in order to sync our timers. If we didn't hear the beacon during this time - we abandon the connection. However, in congested environment, it was observed we might not hear beacons in that time slot. Extend the time event to give the connection a better chance.

Thermal zone device registration can fail, and in this case we don't want to remove WiFi functionality. This is why the thermal zone registration function is void, and the flows continue even if the thermal zone device registration failed. Same applies for the cooling device. This means that we at least need to remember that the thermal zone device didn't register properly and take the minimal precautions to avoid panic'ing when we access it. This was missing.

The pci driver keeps any unbound device in active state and forbids runtime PM. When our driver gets probed, we take control of the state. When the device is released (i.e. during unbind or module removal), we should return the state to what it was before. To do so, we need to forbid RTPM in the driver remove op. Additionally, remove an unnecessary pm_runtime_disable() call, move the initial ref_count setting to a better place and add some comments explaining what is going on.

Beacon abort (ba) is set while sending power command, but only after at least one beacon_filter command was successfully sent. If we heard a beacon before starting association, this order is maintained and ba is properly set. However, if the first beacon is received after association, we send the power command upon association, configure the beacon filtering when the first beacon arrives, and in that case, beacon abort is not set. So identify this, and send a power command post the beacon_filter command if needed.

In multi rx queue HW, without execessive locking, there is no sync between the ctrl path (default queue) and the rest of the rx queues. This might cause issues on certain situations. For example, in case a delBA was processed on a default queue but out of order packets still wait for processing on the other queue. The solution is to introduce internal messaging between the CTRL path and the other rx queues. The driver will send a message to the firmware, which will echo it to all the requested queues. The message will be in order inside the queue. This way we can avoid CTRL path and RSS queues races. Add support for this messaging mechanism. As the firmware is agnostic to the data sent, add internal representation of the data as well. Although currently only delBA flow will use it, the internal representation will enable generic use of this infrastructure for future uses. Next patch will utilize this messaging mechanism for the reorder buffer delBA flow. Signed-off-by: NSara Sharon <sara.sharon@intel.com> Signed-off-by: NEmmanuel Grumbach <emmanuel.grumbach@intel.com>

Next hardware will direct TCP/UDP streams to different cores. Packets belonging to the same stream will be directed to the same core. The result is that duplicates will be always directed to the same rx queue were the first packet was received.
