This function is not needed: * we already have the "cmd" input to it in the same type (and on the stack elsewhere) * the "legacy_reserved" parameter is never set, so will always be zero Remove the function and the stack copy of the input command. This is still left from when iwlegacy was part of the driver -- then we needed a translation for the command for 3945. Signed-off-by:

Add new IO function _iwl_write_targ_mem_words() to support target memory write for a continuous area. It will return error code -EBUSY if iwl_grab_nic_access() fails to indicate the memory write does not be performed. Meanwhile the existing function iwl_write_targ_mem() also been updated by using _iwl_write_targ_mem_words() in a single word case. Signed-off-by:

If the agg SM is in IWL_EMPTYING_HW_QUEUE_ADDBA or in IWL_EMPTYING_HW_QUEUE_DELBA, we are not supposed to get Tx packets from mac80211. mac80211 is supposed to buffer these packets for us. A few issues have been identified in this mechanism, not all of them were fixed. Signed-off-by:

Since my latest patches, the upper layer reports to mac80211 that the driver is ready to continue the start / stop BA flow as opposed to the transport layer. Hence, iwl_{start,stop}_tx_ba_trans_ready are not needed any more. Signed-off-by: -

In the very first implementation of HT, the driver was responsible for the queueing: stopping and waking the queues while the HW queues where being drained. In this implementation, we had to deal with the case where we were draining the AGG queue because we wanted to tear down the BA agreement. In the normal flow (when we don't drain any HW queue), when packets are reclaimed, we wake the SW queue in case the SW queue was stopped which can happen when the HW queues are too full. While draining a HW queue, we must make sure that we don't wake the SW queue, since the whole point of the draining is to empty totally the HW queue and not only get below a certain threshold. This is why there is condition in the reclaim function: if (NOT EMPTYING DELBA) wake the SW queue is applicable Since then, a lot has changed and mac80211 is now able to buffer packets that are being sent to a packet list that will be spliced after the driver has reported it has drained its HW queues. Hence, there is no need for the for aforementioned if, and we can safely wake up the queue even if we are draining HW queues. Removing this if, also allows us to remove the wake_queue in check_empty that was there in order to deal with a corner case created by the if. 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:

When we restore regulatory settings the world regulatory domain is properly reset on cfg80211 (or user prefered regulatory domain) but we were never setting back channel values for drivers that use WIPHY_FLAG_CUSTOM_REGULATORY. Set these values up again by using the orig_ channel parameters. This fixes restoring custom regulatory settings upon disconnect events.

By definition WIPHY_FLAG_STRICT_REGULATORY was intended to allow the wiphy to adjust itself to the country IE power information if the card had no regulatory data but we had no way to tell cfg80211 that if the card also had its own custom regulatory domain (these are typically custom world regulatory domains) that we want to follow the country IE's noted values for power for each channel. We add support for this and document it. This is not a critical fix but a performance optimization for cards with custom regulatory domains that associate to an AP with sends out country IEs with a higher EIRP than the one on the custom regulatory domain. In practice the only driver affected right now are the Atheros drivers as they are the only drivers using both WIPHY_FLAG_STRICT_REGULATORY and WIPHY_FLAG_CUSTOM_REGULATORY -- used on cards that have an Atheros world regulatory domain. Cards that have been programmed to follow a country specifically will not follow the country IE power. So although not a stable fix distributions should consider cherry picking this.

This initial DFS module provides basic functionality to deal with radar pulses reported by the Atheros DFS HW pulse detector. The reported data is evaluated and basic plausibility checks are performed to filter false pulses. Passing radar pulses are forwarded to pattern detectors which are not yet implemented.
