Paprd needs to be done only on active chains(not for all the chains that hw can support). The paprd training frames which are sent for inactive chains would be hanging on the hw queue without getting transmitted and would make the connection so unstable. This issue happens only with the hw which supports paprd cal(ar9003). Signed-off-by:

This patch fixes stale mac80211_tx_control_flags for filtered / retried frames. Because ieee80211_handle_filtered_frame feeds skbs back into the tx path, they have to be stripped of some tx flags so they won't confuse the stack, driver or device. Cc: <stable@kernel.org> Acked-by:

The "basic_rate" module option is not implemented correctly. If the rate was set to zero it was supposed to set it to "basic_rate | 0x80". Unfortunately the check to see if what zero was wrong and it checked "!ai->config.rates" (which is always false) instead of "!ai->config.rates[i]". This option was just used for development and it wasn't documented anywhere. Instead of fixing it, we can just remove it. Reported-by:

IEEE Std 802.11k-2008 added DS Parameter Set information element into Probe Request frames as an optional information on 2.4 GHz band (and mandatory, if radio measurements are enabled). This allows APs to filter out Probe Request frames that may be received from neighboring overlapping channels and by doing so, reduce the number of unnecessary frames in the air. Make mac80211 add this IE into Probe Request frames whenever the channel is known (i.e., whenever hwscan is not used). Signed-off-by:

commit 8c0c709e Author: Johannes Berg <johannes@sipsolutions.net> Date: Wed Nov 25 17:46:15 2009 +0100 mac80211: move cmntr flag out of rx flags moved the CMTR flag into the skb's status, and in doing so introduced a use-after-free -- when the skb has been handed to cooked monitors the status setting will touch now invalid memory. Additionally, moving it there has effectively discarded the optimisation -- since the bit is only ever set on freed SKBs, and those were a copy, it could never be checked. For the current release, fixing this properly is a bit too involved, so let's just remove the problematic code and leave userspace with one copy of each frame for each virtual interface.

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:

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).
