When disabling TX aggregation because it was rejected or from the timer (it was not accepted), there is a window where we first set the state to operation, unlock, and then undo the whole thing. Avoid that by splitting up the stop function. Also get rid of the pointless sta_info indirection in the timer. Signed-off-by:

Doing so would be an MLME protocol violation when the peer disabled the aggregation session. Quick driver review indicates that there are error codes passed all over the drivers but cannot ever be nonzero except in error conditions that would indicate mac80211 bugs. No real changes here, since no drivers currently can return -EBUSY. Signed-off-by:

We can only support aggregation on AP/STA right now. HT isn't defined for IBSS, WDS or MESH. In the WDS/MESH cases it's not clear what to put into the IBSS field, and we don't handle that in the code at all. Also fix the code to handle VLAN correctly. Signed-off-by:

It's a little confusing to get the BSSID outside the function and pass it in, when it's only needed for this function, so change that. Signed-off-by:

Hopefully the last required fix ... disable beaconing only on beaconing interfaces, and thus avoid calling ieee80211_if_config for purely virtual interfaces (those driver doesn't know about). Signed-off-by:

This makes zd1211rw honour enable_beacon, as well as fixing a memory leak: the beacon skb is leaked when configuring it to the hardware fails. Signed-off-by:

Before we have a probe response frame (which is used as the beacon too) there's no need to ask drivers to beacon, they will not get a beacon anyway. Signed-off-by:

It is rather confusing to see this in the log: [ 695.606877] __ratelimit: 40 callbacks suppressed [ 700.726878] __ratelimit: 40 callbacks suppressed without ever seeing any actual message. This is because zd1211rw doesn't compile out the net_ratelimit() call properly if debugging is not enabled. Signed-off-by:

When a directed tim bit is set, mac80211 currently disables power save ands sends a null frame to the AP. But if dynamic power save is disabled, mac80211 will not enable power save ever gain. Fix this by adding ps-poll functionality to mac80211. When a directed tim bit is set, mac80211 sends a ps-poll frame to the AP and checks for the more data bit in the returned data frames. Using ps-poll is slower than waking up with null frame, but it's saves more power in cases where the traffic is low. Userspace can control if either ps-poll or null wakeup method is used by enabling and disabling dynamic power save. Signed-off-by:

Currently mac80211 checks for the multicast tim bit from beacons, disables power save and sends a null frame if the bit is set. This was added to support ath9k. But this is a bit controversial because the AP will send multicast frames immediately after the beacon and the time constraints are really high. Relying mac80211 to be fast enough here might not be reliable in all situations. And there's no need to send a null frame, AP will send the frames immediately after the dtim beacon no matter what. Also if dynamic power save is disabled (iwconfig wlan0 power timeout 0) currently mac80211 disables power save whenever the multicast bit is set but it's never enabled again after receiving the first multicast/broadcast frame. The current implementation is not usable on p54/stlc45xx and the easiest way to fix this is to remove the multicast tim bit check altogether. Handling multicast tim bit in host is rare, most of the designs do this in firmware/hardware, so it's better not to have it in mac80211. It's a lot better to do this in firmware/hardware, or if that's not possible it could be done in the driver. Also renamed the function to ieee80211_check_tim() to follow the style of the file.

* We call reset too often and this can result various PHY problems. On config_interface we don't need to reset the whole device. TODO: Create a function hw_fast_reset that only resets the PCU (tx/rx stuff) and not the whole device so that we can use this for stuck beacons etc. Signed-off-by:

* Update and cleanup rf gain optimization code * Add comments and refferences to docs and use sane function names * Use only step index on ath5k_gain, no need to have a pointer to the current step since we can determine te step from it's index, this also allows us to put all other structs on rfgain.h and cleanup ath5k.h a little * No need for ah_rfgain variable, we use ah_gain.g_state for everything * Tested on RF2112B chip but gain_F calibration is not yet done (we will finish this on the next patch where we'll rewrite rf-buffer handling) * Use initial rf gain settings for 2316 and 2317 SoCs introduced on a previous patch It seems big but it's mostly cleanup, very few functional changes have been made on phy.c Signed-off-by:

* Clean up initial rf buffer settings (new file rfbufer.h) and introduce a new way to access specific rf registers (will use it later) * Clean up initial rf gain settings by moving them on a new file (rfgain.h) so we can later work on gain optimization functions * Update initial rf buffer settings and initial rf gain settings from HALs. This breaks things for now because our current dumps come from pre-configured rf buffer (regdumps already had the needed values set from binary HAL). Signed-off-by:

The atomic requirement for the TSF callbacks is outdated. get_tsf() is only called by ieee80211_rx_bss_info() which is indirectly called by the work queue ieee80211_sta_work(). In the same context are called several other non-atomic functions, too. And the atomic requirement causes problems for drivers of USB wifi cards. Signed-off-by:

This issue happens only when we are associated with a 11n AP and power save is enabled. In the function 'ieee80211_master_start_xmit', ps_disable_work is queued where wake_queues is called. But before this work is executed, we check if the queues are stopped in _ieee80211_tx and return TX_AGAIN to ieee8011_tx which leads to the warning message. This patch fixes this erroneous case.
