The tid aggregation cleanup is a bit fragile, as it discards failed subframes in some places, and retransmits them in others. This could block the cleanup of an existing aggregation session, if a retransmission for a tid is issued, yet the tid is never scheduled again because of the cleanup state. Fix this by getting rid of as many subframes as possible, as early as possible, and immediately transmitting pending subframes as regular HT frames instead of waiting for the cleanup to complete. Drop all pending subframes while keeping track of the Block ACK window during aggregate tx completion to prevent sending out stale subframes, which could confuse the receiver side. Signed-off-by:

A new aggregation session start can be issued by mac80211, even when the cleanup of the previous session has not completed yet. Since the data structure for the session is not recreated, this could corrupt the block ack window and lock up the aggregation session. Fix this by delaying the new session until the old one has been cleaned up. Signed-off-by:

There's no reason to keep pointers to pending tx buffers around, if they're only used to keep track of which frames are still pending. Use a bitfield instead. Signed-off-by:

Don't mark the device as completely dead just yet. If all goes to plan and carl9170_reboot succeeds then we can skip the expensive userspace-driven reinitialization anyway. And if it doesn't and carl9170_reboot fails, then carl9170_usb_cancel_urbs will do the necessary steps. Signed-off-by:

Ever since carl9170 gained support to read the noisefloor, the reported noisefloor level was pretty poor. Initially I assumed that something was wrong in the PHY setup and it would be impossible to fix without any guidances. But this was not the case. In fact the nf readings were correct and the thing that was broken was the "simple" sign extension code! Signed-off-by:

Get rid of overly complicated cw_min/max and AIFS configuration: * Validate values in ath5k_hw_set_tx_queueprops(), so we can use them directly without further checks or computation in ath5k_hw_reset_tx_queue(). * Simplifiy by using AR5K_TUNE_AIFS|CWMIN|CWMAX variables directly since we don't support XR or B channels. That way we can also remove AR5K_TXQ_USEDEFAULT and the confusing logic around it. * Update data types: AIFS is u8, CW's are u16. * Remove now unneeded variables in ath5k_hw. Signed-off-by:

If we return a TX descriptor to the pool of available descriptors, while a queues TXDP still points to it we could potentially run into all sorts of troube. It has been suggested that there is hardware which can set the descriptors done bit before it reads ds_link and moves on to the next descriptor. While the documentation says this is not true for newer chipsets (the descriptor contents are copied to some internal memory), we don't know about older hardware. To be safe, we always keep the last descriptor in the queue, and avoid dangling TXDP pointers. Unfortunately this does not fully resolve the problem - queues still get stuck! This is similar to what ath9k does. Signed-off-by:

Prepare ath5k for WME by using four hardware queues. The way we set up our queues matches the mac80211 queue priority 1:1, so we don't have to do any mapping for queue numbers. Every queue uses 50 of the total 200 available transmit buffers, so the DMA memory usage does not increase with this patch, but it might be good to fine-tune the number of buffers per queue later (depending on the CPU speed and load, and the speed of the medium access, it might not be big enough).
