Enable logging of more configuration data when tracing is enabled. Except for the channel frequency this is only useful with the binary trace format, but that can be recorded and replayed with trace-cmd and I will be working on a plugin that reports all the information. Signed-off-by:

As indicated by the comment, the aMPDU RX reorder code should logically be after ieee80211_rx_h_check(). The previous patch moved the code there, and this patch now hooks it up in that place by introducing a list of skbs that are then processed by the remaining handlers. The list may be empty if the function is buffering the skb to release it later. The only change needed to the RX data is that the crypto handler needs to clear the key that may be set from a previous loop iteration, and that not everything can be in the rx flags now.

This code should be part of RX handlers, so move it to the place where it belongs without changing it. A follow-up patch will do the changes to hook it up. The sole purpose of this code move is to make the other patch readable, it doesn't change the code at all except that it now requires a different static function declaration (which will go away too).

The RX flags should soon be used only for flags that cannot change within an a-MPDU, so move the cooked monitor flag into the RX status flags. Signed-off-by:

This patch moves the works cleanup, scan and events to a cfg80211 dedicated workqueue. Platform driver like eeepc-laptop ought to use works to rfkill (as new rfkill does lock in rfkill_unregister and the platform driver is called from rfkill_switch_all which also lock the same mutex). This raise a new issue in itself that the work scheduled by the platform driver to the global worqueue calls wiphy_unregister which flush_work scan and event works (which thus flush works on the global workqueue inside a work on the global workqueue) and also put on hold the wdev_cleanup_work (which prevents the dev_put on netdev thus indefinite Usage count error on wifi device).

mesh.c will be the file where we concentrate all mesh-related code. This allows us to either add a KConfig entry for mesh and makes matters easier for the cfg80211 transition. Signed-off-by:

Update the beacon queue parameters with best effort queue parameters for IBSS mode. This reduces the number of beacons generated by ath9k and ensures a fair beacon distribution when there are multiple IBSS stations. Also CWmin is quadrupled to achieve the expected percentage of distribution. Signed-off-by:

Atheros single stream AR9285 and AR9271 have half the PCU TX FIFO buffer size of that of dual stream devices. Dual stream devices have a max PCU TX FIFO size of 8 KB while single stream devices have 4 KB. Single stream devices have an issue though and require hardware only to use half of the amount of its capable PCU TX FIFO size, 2 KB and this requires a change in software. Technically a change would not have been required (except for frame burst considerations of 128 bytes) if these devices would have been able to use the full 4 KB of the PCU TX FIFO size but our systems engineers recommend 2 KB to be used only. We enforce this through software by reducing the max frame triggger level to 2 KB. Fixing the max frame trigger level should then have a few benefits: * The PER will now be adjusted as designed for underruns when the max trigger level is reached. This should help alleviate the bus as the rate control algorithm chooses a slower rate which should ensure frames are transmitted properly under high system bus load. * The poll we use on our TX queues should now trigger and work as designed for single stream devices. The hardware passes data from each TX queue on the PCU TX FIFO queue respecting each queue's priority. The new trigger level ensures this seeding of the PCU TX FIFO queue occurs as designed which could mean avoiding false resets and actually reseting hw correctly when a TX queue is indeed stuck. * Some undocumented / unsupported behaviour could have been triggered when the max trigger level level was being set to 4 KB on single stream devices. Its not clear what this issue was to me yet.

Software padding is done on the TX path and software unpadding is done on the RX path. This patch corrects the position where the padding occurs. A specific function computes the pad position and this function is used in the TX and RX path. This patch has been tested by generating every possible 802.11 frames with every possible frame_control field and a varying length. This patch is useful for analyzing non standard 802.11 frames going over the air Signed-off-by:

When mac80211 was telling us to go into Powersave we listened and immediately turned RX off. This meant hardware would not see the ACKs from the AP we're associated with and hardware we'd end up retransmiting the null data frame in a loop helplessly. Fix this by keeping track of the transmitted nullfunc frames and only when we are sure the AP has sent back an ACK do we go ahead and shut RX off. Signed-off-by:

To support 802.11n Tx aggregation support with iwmc3200 wifi, we have to handle the UMAC_CMD_OPCODE_STOP_RESUME_STA_TX notification from the UMAC. Before sending an AddBA, the UMAC synchronizes with the host in order to know what is the last Tx frame it's supposed to receive before it will be able to start the actual aggregation session. We thus have to keep track of the last sequence number that is scheduled for transmission on a particular RAxTID, send an answer to the UMAC with this sequence number. The UMAC then does the BA negociation and once it's done with it sends a new UMAC_CMD_OPCODE_STOP_RESUME_STA_TX notification to let us know that we can resume the Tx flow on the specified RAxTID.

We were missing the command header in the radio and general parameters commands. This was causing them to fail, resulting in problems in the power levels and other PLT-related commands. Also reorganized the command functions, moving from wl1271_init.c to wl1271_cmd.c where it fits better. Signed-off-by:

The wl1271_dev_notify() was returning 0 or -ENODEV, when it should return NOTIFY_* instead. Now we use NOTIFY_DONE when we didn't handle the event or NOTIFY_OK when we have handled it. For inetdev notifications, it doesn't matter whether we use NOTIFY_DONE or NOTIFY_OK, because it ignores the return value of the call to blocking_notifier_call_chain(). But the notify.h header says that NOTIFY_DONE is "Don't care" and NOTIFY_OK is "Suits me", so that seems to be the right way to do it. Reported-by:
