2014-12-02iwlwifi: mvm: update values for Smart FifoEmmanuel Grumbach1-1/+1
Interoperability issues were identified and root caused to the Smart Fifo watermarks. These issues arose with NetGear R7000. Fix this.

2014-12-02iwlwifi: dvm: fix flush support for old firmwareEmmanuel Grumbach2-36/+42
Since the commit below, iwldvm sends the FLUSH command to the firmware. All the devices that use iwldvm have a firmware that expects the _v3 version of this command, besides 5150. 5150's latest available firmware still expects a _v2 version of the FLUSH command. This means that since the commit below, we had a mismatch for this specific device only. This mismatch led to the NMI below: Loaded firmware version: 8.24.2.2 Start IWL Error Log Dump: Status: 0x0000004C, count: 5 0x00000004 | NMI_INTERRUPT_WDG 0x000006F4 | uPc 0x000005BA | branchlink1 0x000006F8 | branchlink2 0x000008C2 | interruptlink1 0x00005B02 | interruptlink2 0x00000002 | data1 0x07030000 | data2 0x00000068 | line 0x3E80510C | beacon time 0x728A0EF4 | tsf low 0x0000002A | tsf hi 0x00000000 | time gp1 0x01BDC977 | time gp2 0x00000000 | time gp3 0x00010818 | uCode version 0x00000000 | hw version 0x00484704 | board version 0x00000002 | hcmd 0x2FF23080 | isr0 0x0103E000 | isr1 0x0000001A | isr2 0x1443FCC3 | isr3 0x11800112 | isr4 0x00000068 | isr_pref 0x000000D4 | wait_event 0x00000000 | l2p_control 0x00000007 | l2p_duration 0x00103040 | l2p_mhvalid 0x00000007 | l2p_addr_match 0x00000000 | lmpm_pmg_sel 0x00000000 | timestamp 0x00000200 | flow_handler This was reported here: https://bugzilla.kernel.org/show_bug.cgi?id=88961 Cc: <stable@vger.kernel.org> Fixes: a0855054e59b ("iwlwifi: dvm: drop non VO frames when flushing") Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
2014-12-02iwlwifi: use correct fw file in 8000 b-stepLiad Kaufman1-0/+54
In 8000 B-step the FW file has changed, but by the time we know the HW step, the FW file is already requested. This patch defaults 8000 family to B-step if no HW step is detected in time. When it can it checks what HW step it really is (in 8000 family) and if it isn't B-step, the FW file is released and the A-step file is requested.

2014-11-24iwlwifi: mvm: protect session during CSALuciano Coelho2-0/+22
When another vif is also running during a channel switch, we need to use a session protection when we move to the new channel, so that we don't miss the beacons. Without this, sometimes the other vif repeatedly gets time exactly when we should be hearing the beacons, preventing channel switch from completing. Adding a session protection that lasts from the moment the channel changes until 2 TBTTs later, ensures that we will hear the beacons on the destination channel.

2014-11-24iwlwifi: mvm: disable beacon filtering during CSALuciano Coelho1-0/+10
After a channel switch, transmission on the new channel is only started once we see a beacon on it. Thus, beacon filtering needs to be disabled during channel switch so that mac80211 receives this beacon and finishes the process. Signed-off-by: Luciano Coelho <luciano.coelho@intel.com>
2014-11-24iwlwifi: mvm: add a channel_switch op to bypass mac80211 timerLuciano Coelho2-0/+16
We need to call ieee80211_chswitch_done() ourselves just when the absence TE started, so we perform the actual context switch early enough. To do so, add a dummy channel_switch op, which will cause mac80211 to skip the countdown timer and allow us to call ieee80211_chswitch_done() to complete the operation.

2014-11-24iwlwifi: mvm: schedule CSA time event a bit before beacon 1Luciano Coelho2-8/+17
Instead of using a hardcoded number of TUs before beacon 0 as the time to start the absence and actual channel switch, calculate it in relation to the beacon interval. We use 10 TUs + beacon interval before beacon 0 to target a bit before beacon 1. This gives us enough time to switch to the new channel before the AP/GO switches.

Add an absent time event when pre_channel_switch is called and use the time event started indication to set the disable_tx bit instead of doing it in unassign_vif(). This is done so that the firmware queues are stopped before the actual switch takes place to avoid losing packets while the AP/GO is performing its actual switch.

The spec requires to decrement the CSA counters based on TBTT, regardless if the beacon was actually transmitted. Previously, the fw would send beacon notifications only for successfully transmitted beacons. This behavior resulted in inaccurate CSA countdown. In order to address this issue, the fw was changed to send beacon notifications also for not transmitted beacons. Such notifications have TX_STATUS_INTERNAL_ABORT (0x92). Don't start the CSA countdown before first successfully transmitted beacon, in order to guarantee that the CSA is announced for a required period.
