2012-09-27wlcore: Fix unbalanced interrupts enablementIdo Yariv
The interrupt line is enabled by wl12xx_enable_interrupts and wl18xx_enable_interrupts, but it will not be disabled in all failure paths. Fix this. Signed-off-by: Ido Yariv <ido@wizery.com> Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <luca@coelho.fi>
2012-09-27wlcore: Don't recover during bootIdo Yariv
While recursive recovery is avoided during shutdown, a new recovery may be queued when the FW boots. The recovery work will then try to stop an already stopped hardware, which will most likely result in a kernel panic. Fix this by verifying that wl->state is on before queueing a new recovery.

2012-09-27wlcore: spi: use private max-buf-size limitArik Nemtsov
Limit SPI transmissions to the wl12xx max buffer size, as only 12xx was tested with SPI. This allows us to remove the global aggregation buffer constant. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <luca@coelho.fi>
2012-09-27wl18xx: number_of_assembled_ant5 indicates if A band is enabledYair Shapira
Use number_of_assembled_ant5 phy param to indicate if A band is enabled: if number_of_assembled_ant5 != 0 then it is enabled otherwise it is disabled. This aligns with phy implementation that uses this param both to indicate if band is active and the number of antennas. This parameter replaces enable_11a module param that was removed. User-Space applications can use wlconf and/or INI files to disable A band using this parameter.

2012-09-27wlcore: lazy-enable device rolesEliad Peller
Enable device roles just before starting it. This way, a single device role should be enough for all vifs, as we can't use concurrent device roles (which require ROC) anyway. Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Luciano Coelho <luca@coelho.fi>
2012-09-27wlcore: always use wlvif->role_id for scansEliad Peller

2012-09-27wlcore: resume() only if sta is associatedEliad Peller
mac80211's resume() callback might get called even if the sta is not associated (but only up). The resume sequence in this case results in configuring the wake-up conditions of a non-started role, which causes fw assertion. Fix it by bailing out if the STA is not connected (like we do on suspend()). Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Luciano Coelho <luca@coelho.fi>
2012-09-27wlcore: configure wowlan regardless of wakeup conditionsEyal Shapira
wowlan filters should be configured in any case in suspend/resume. This shouldn't be dependent on whether wakeup conditions are the same for suspend and resume states. Only the FW command to reconfigure wakeup conditions should be avoided in such a case.

2012-09-27wlcore: tx_flush - optimize flow and force Tx during the flushArik Nemtsov
Force Tx during the flush if there are packets pending in the driver. This actually solves a bug where we would get called from the mac80211 wq context, which would prevent tx_work from getting queued, even when the mutex is unlocked. Don't stop the queues needlessly if there's nothing to flush. Use a larger delay when sleeping to give the driver a chance to flush and avoid cpu busy looping. Re-arrange the loop so the last iteration is not wasted. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <luca@coelho.fi>

2012-09-27wlcore: allow only the lowest OFDM rate for p2p setup framesArik Nemtsov
The IEEE80211_TX_CTL_NO_CCK_RATE flag is only set for mgmt packets transmitted during p2p connection setup. Make sure to use the lowest OFDM rate guarantee the peer always hears us. Change the p2p rate policy to contain only the 6mpbs rate to acheive this effect. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <luca@coelho.fi>
2012-09-27wlcore: AP mode - send non-data packets with basic ratesArik Nemtsov

2012-09-27wlcore: cancel recovery_work on stop() instead of remove_interface()Eliad Peller

2012-09-27wlcore: Prevent interaction with HW after recovery is queuedIdo Yariv
When a function requests to recover, it would normally abort and will not send any additional commands to the HW. However, other threads may not be aware of the failure and could try to communicate with the HW after a recovery was queued, but before the recovery work began. Fix this by introducing an intermediate state which is set when recovery is queued, and modify all state checks accordingly.

2012-09-27wlcore: consider single fw caseEliad Peller
When a single fw is being used for both single-role and multi-role cases (e.g. 18xx), wl->mr_fw_name is NULL, which results in NULL dereference while trying to load the multi-role fw. In this case, always use the single-role fw, and avoid redundant fw switch by checking for this case in wl12xx_need_fw_change() as well.

2012-09-25ath9k_hw: fix BT sleep state on chip wakeupRajkumar Manoharan
Whenever both WLAN and BT in/out sleep mode, sometimes WLAN is not able to take back the shared LNA control after resumes from sleep mode. The idea is that for WLAN to check if BT owns LNA control and BT is in sleep mode when WLAN just resumes from sleep mode. If the condition is true, do a BTCOEX_RC_WARM_RESET for WLAN to take back the control of shared LNA. Now the issue is the BT sleep value read from MCI register is overlooked by assigning u32 into u8. Hence the above condition never be met so that WLAN used to report beacon losses and frequent connection drops.

2012-09-25ath9k: Disable ASPM only for AR9285Sujith Manoharan
Currently, ASPM is disabled for all WLAN+BT combo chipsets when BTCOEX is enabled. This is incorrect since the workaround is required only for WB195, which is a AR9285+AR3011 combo solution.

With this one we get: - HCI and LLC layers separation. We now can support various LLC protocols for HCI drivers, SHDLC being one of them. This will be needed as we're planning to support raw HCI chipsets that do the SHDLC encapsulation in firmware. So for now we have an SHDLC and a NOP LLC layers. - pn533 command queueing implementation. This simplifies the pn533 locking logic and fixes a kernel warning. - NCI p2p initiator mode implementation. - Replace custom workqueues with system ones, for HCI and LLCP. - Raw pn544 driver removal, as scheduled on the features-removal.txt file. - A few HCI, SHDLC and LLCP fixes.

2012-09-25cfg80211: Fix regulatory check for 60GHz band frequenciesVladimir Kondratiev
The current regulatory code on cfg80211 performs a check to see if a regulatory rule belongs to an IEEE band so that if a Country IE is received and no rules are specified for a band (which is allowed by IEEE) those bands are left intact. The current band check assumes a rule is bound to a band if the rule's start or end frequency is less than 2 GHz apart from the center of frequency being inspected. In order to support 60 GHz for 802.11ad we need to increase this to account for the channel spacing of 2160 MHz whereby a channel somewhere in the middle of a regulatory rule may be more than 2 GHz apart from either the beginning or end of the frequency rule. Without a fix for this even though channels 1-3 are allowed world wide on the rule (57240 - 63720 @ 2160), channel 2 at 60480 MHz will end up getting disabled given that it is 3240 MHz from both the frequency rule start and end frequency. Fix this by using 2 GHz separation assumption for the 2.4 and 5 GHz bands but for 60 GHz use a 10 GHz separation before assuming a rule is not part of the band. Since we have no 802.11ad drivers yet merged this change has no impact to existing Linux upstream device drivers. Signed-off-by: Vladimir Kondratiev <qca_vkondrat@qca.qualcomm.com> Acked-by: Luis R.
