Adrian Chadd f5c30c4e8d 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		2014-04-30 02:19:41 +00:00
