Pause and unpause the software queues for a given node based on the net80211 node power save state. * Add an ATH_NODE_UNLOCK_ASSERT() check * Add a new node field - an_is_powersave * Pause/unpause the queue based on the node state * Attempt to handle net80211 concurrency issues so the queue doesn't get paused/unpaused more than once at a time from the net80211 power save code. Whilst here (and breaking my usual rule), set CLRDMASK when a queue is unpaused, regardless of whether the queue has some pending traffic. This means the first frame from that TID (now or later) will hvae CLRDMASK set. Also whilst here, bump the swretrymax counters whenever the filtered frames code expires a frame. Again, breaking my rule, but this is just a statistics thing rather than a functional change. This doesn't fix ps-poll (but it doesn't break it too much worse than it is at the present) or correcting the TID updates. That's next on the list. Tested: * AR9220 AP (Atheros AP96 reference design) * Macbook Pro and LG Optimus 1 Android phone, both setting and clearing power save state (but not using PS-POLL.)

ATH_DEBUG_NODE_PWRSAVE = 0x800000000ULL, /* node powersave */
Migrate the LNA mixing diversity machinery from the AR9285 HAL to the driver. The AR9485 chip and AR933x SoC both implement LNA diversity. There are a few extra things that need to happen before this can be flipped on for those chips (mostly to do with setting up the different bias values and LNA1/LNA2 RSSI differences) but the first stage is putting this code into the driver layer so it can be reused. This has the added benefit of making it easier to expose configuration options and diagnostic information via the ioctl API. That's not yet being done but it sure would be nice to do so. Tested: * AR9285, with LNA diversity enabled * AR9285, with LNA diversity disabled in EEPROM

ATH_DEBUG_DIVERSITY = 0x1000000000ULL, /* Diversity logic */
Bring over some initial power save management support, reset path fixes and beacon programming / debugging into the ath(4) driver. The basic power save tracking: * Add some new code to track the current desired powersave state; and * Add some reference count tracking so we know when the NIC is awake; then * Add code in all the points where we're about to touch the hardware and push it to force-wake. Then, how things are moved into power save: * Only move into network-sleep during a RUN->SLEEP transition; * Force wake the hardware up everywhere that we're about to touch the hardware. The net80211 stack takes care of doing RUN<->SLEEP<->(other) state transitions so we don't have to do it in the driver. Next, when to wake things up: * In short - everywhere we touch the hardware. * The hardware will take care of staying awake if things are queued in the transmit queue(s); it'll then transit down to sleep if there's nothing left. This way we don't have to track the software / hardware transmit queue(s) and keep the hardware awake for those. Then, some transmit path fixes that aren't related but useful: * Force EAPOL frames to go out at the lowest rate. This improves reliability during the encryption handshake after 802.11 negotiation. Next, some reset path fixes! * Fix the overlap between reset and transmit pause so we don't transmit frames during a reset. * Some noisy environments will end up taking a lot longer to reset than normal, so extend the reset period and drop the raise the reset interval to be more realistic and give the hardware some time to finish calibration. * Skip calibration during the reset path. Tsk! Then, beacon fixes in station mode! * Add a _lot_ more debugging in the station beacon reset path. This is all quite fluid right now. * Modify the STA beacon programming code to try and take the TU gap between desired TSF and the target TU into account. (Lifted from QCA.) Tested: * AR5210 * AR5211 * AR5212 * AR5413 * AR5416 * AR9280 * AR9285 TODO: * More AP, IBSS, mesh, TDMA testing * Thorough AR9380 and later testing! * AR9160 and AR9287 testing Obtained from: QCA

Replay r286410. Change KPI of how device drivers that provide wireless connectivity interact with the net80211 stack. Historical background: originally wireless devices created an interface, just like Ethernet devices do. Name of an interface matched the name of the driver that created. Later, wlan(4) layer was introduced, and the wlanX interfaces become the actual interface, leaving original ones as "a parent interface" of wlanX. Kernelwise, the KPI between net80211 layer and a driver became a mix of methods that pass a pointer to struct ifnet as identifier and methods that pass pointer to struct ieee80211com. From user point of view, the parent interface just hangs on in the ifconfig list, and user can't do anything useful with it. Now, the struct ifnet goes away. The struct ieee80211com is the only KPI between a device driver and net80211. Details: - The struct ieee80211com is embedded into drivers softc. - Packets are sent via new ic_transmit method, which is very much like the previous if_transmit. - Bringing parent up/down is done via new ic_parent method, which notifies driver about any changes: number of wlan(4) interfaces, number of them in promisc or allmulti state. - Device specific ioctls (if any) are received on new ic_ioctl method. - Packets/errors accounting are done by the stack. In certain cases, when driver experiences errors and can not attribute them to any specific interface, driver updates ic_oerrors or ic_ierrors counters. Details on interface configuration with new world order: - A sequence of commands needed to bring up wireless DOESN"T change. - /etc/rc.conf parameters DON'T change. - List of devices that can be used to create wlan(4) interfaces is now provided by net.wlan.devices sysctl. Most drivers in this change were converted by me, except of wpi(4), that was done by Andriy Voskoboinyk. Big thanks to Kevin Lo for testing changes to at least 8 drivers.
