The tid_data is not related to the transport layer, so move the logic that depends on it to the upper layer. This patch deals with the mapping of RA / TID to HW queues in AGG. Signed-off-by:

Since packets sent to an RA / TID in AGG are sent from a separate HW Tx queue, we may get into a race: the regular queue isn't empty while we already begin to send packets from the AGG queue. This would result in sending packets out of order. In order to cope with this, mac80211 waits until the driver reports that the legacy queue is drained before it can send packets to the AGG queue. During that time, mac80211 buffers packets for the driver. These packets will be sent in order after the driver reports it is ready. The way this was implemented in the driver is as follows: We held a counter that monitors the number of packets for an RA / TID in the HW queues. When this counter reached 0, we knew that the HW queues were drained and we reported to mac80211 that were ready to proceed. This patch changes the implementation described above. We now remember what is the wifi sequence number of the first packet that will be sent in the AGG queue (lets' call it ssn). When we reclaim the packet before ssn, we know that the queue is drained, and we are ready to proceed. This will allow us to move this logic in the upper layer and eventually remove the tid_data from the shared area. Signed-off-by:

The current default watchdog timer is enabled, but we are seeing issues on legacy devices. So change the default setting of watchdog timer to per device based. But user still can use the "wd_disable" module parameter to overwrite the system setting Cc: stable@vger.kernel.org #3.0+ Signed-off-by:

The init microcode knows very well which calibrations are required and sends us results for those that are. Consequently, we can just send all of those to the RT uCode again. The problem with having the driver know about this is that it is a uCode feature, not a hardware feature so the config is completely unsuitable. The only thing we need to check is whether the device needs crystal calibration or not, add a new parameter to the configuration for that. This makes new uCode work on 6000 series devices.

When we cancel a scan, the completion runs only from the workqueue. This can cause the remain-on-channel scan to fail when another one was just canceled, because we're still aborting it. To fix this, run the completion inline with the lock still held before returning from iwl_scan_cancel_timeout(). Also, to avoid the scan complete work from completing a new scan prematurely, add a new STATUS_SCAN_COMPLETE bit. Reported-by:

Before this patch, the upper layer could register a callback for each host command. This mechanism allowed the upper layer to have different callbacks for the same command ID. In fact, it wasn't used and the rx_handlers is enough: same callback for all the command with a specific command ID. The iwl_send_add_station needs the access the command that was sent while handling the response (regardless if the command was sent in SYNC or ASYNC mode). So now, all the handlers receive the host command that was sent. This implies a change in the handler signature. Signed-off-by:

This reaches encapsulation for this file. In order to reach this: * move priv->valid_context to iwl_shared * move the last_rejected initialization to the upper layer * define a wrapper iwl_nic_config in the upper layer that calls to cfg->lib->ops->nic_config Signed-off-by:

Move a few declarations needed by the transport layer to iwl-shared.h Move iwl_cmd_meta, iwl_tx_queue and friends to the internal transport header file. Move iwl_device_cmd iwl_host_cmd and friends to iwl-trans.h since these structs are used in the API to the transport layer. Move get_cmd_string to the upper layer with a declaration in iwl-shared.h.

This logic is responsible to tell mac80211 when the HW queues are empty and the BA session can be started / torn down. Fix a bug on the way: When the the Tx BA session is stopped and the HW queues aren't empty, we stop the SW queue to drain the HW queue and then switch to the legacy HW queue. This is the IWL_EMPTYING_HW_QUEUE_DELBA state. While in this state, we never wake the SW queue, even when the HW queue is almost empty, since we need to drain it completely. Look at iwl_trans_pcie_reclaim regarding this. Once the HW queue is really empty, we must wake the SW queue in order to get traffic to the legacy queue. This step was missing leading to an odd situation were the traffic would just stall after we tore down a Tx BA session while the HW queue was not empty. Signed-off-by:

the mapping tx_queue -> fifo is really transport related. The upper layer should be involved in such things. Note that upon agg_disable, the queue is always mapped to fifo 0, but this doesn't matter since when the queue will be setup again for a new BA session, it will be configured to the good fifo anyway.

The rate scaling and the transport need to access the data in iwl_tid_data, hence the move. Note that the only component in the upper layer that needs this data is the rate scaling. Refactoring the rate scaling may help to move iwl_tid_data from the shared area to the transport area. Signed-off-by:
