There's no need to have the transport layer have a callback for iwl_trans_send_cmd_pdu() since it is just a generic wrapper around iwl_trans_send_cmd(). Signed-off-by:

After driver split and no need to support legacy devices, there is no reason we need to separate the NVM access into different files, merge those. Signed-off-by:

From time to time, we hit a WARN_ON in iwl_mac_remove_interface. This basically means that we got out of sync with mac80211: the vif we hold differs from the vif 80211 passes as parameter. Try to get some data that will help to debug this. Signed-off-by:

When a non-empty Tx queueis freed, the buffer it contains must be freed too. Since the Tx cmd are now allocated from a pool, the Tx cmd must be freed too. This patch avoids to destroy a non-empty pool of Tx cmd. Signed-off-by:

If the driver is unloaded while there is still a host command in flight, its tfd will be freed by iwl_tx_queue_free. This function is called for both types of queues: Tx queues and cmd queue. This didn't take in count the fact that in Tx queues, tfds are mapped as TO_DEVICE (besides the first TB), whereas in cmd queue, all TBs are mapped as BIDI. Hence, tx_queue_free unmapped the second (and higher) TB of each tfd in the cmd queue as TO_DEVICE, whereas they must be freed as BIDI. This means that if a multi TFD is in flight while we unload the driver (which is quite unlikely but can happen), we will get the warning below. This patch fixes this.

The way we check if there is host command that should be reclaimed is way too complicated. We should have a clear indication from the fw. The fw is expected to set the SEQ_RX_FRAME bit if the frame was originated by the fw which indicates to the driver that there is no host command to free. Somehow, there seem to have been buggy fw out there, hence the very old comment. This code checks if we have still buggy fw out there. Signed-off-by:

Not doing so, the caldata continues to retain older history values learned on that channel. It is always safer to start noise floor calibration from the defaults after the assoication. So this patch resets the nf history buffer when none of the STA vifs are associated. Signed-off-by:

Currently during the full reset, the nf calibration is always restarted from the defaults. The noise floor history buffers are never be used again after the scan and ath reset. This patch ensures that nf histories are always be used that helps to improve the signal quality on congested environment Signed-off-by:

Do the magnitude/phase coeff correction only if the outlier is detected. Updating wrong magnitude/phase coeff factor impacts not only tx gain setting but also leads to poor performance in congested networks. In the clear environment the impact is very minimal because the outlier happens very rarely according to the past experiment. It occured less than once every 1000 calibrations.

ath9k_hw_set_diversity is only called from init.c where it cannot affect the hardware setting because it's cleared on the next reset. Instead of using a PHY op for something that's supposed to be initialized statically, set the register value directly in the INI override function. Signed-off-by:

With the new EDMA descriptor format, a single descriptor can contain up to four buffer pointers. By splitting the buffer into two parts, we can let the hardware add the padding internally instead of using memmove on the skb data. Signed-off-by:

The only flag that needs to be set when ath_tx_rc_status is called with rc_update == false is the IEEE80211_TX_STAT_TX_FILTERED flag. All other data is ignored in that case. This flag can be set from ath_tx_complete_buf instead, so that we can drop a few redundant calls to ath_tx_rc_status and remove the rc_update function parameter Signed-off-by:
