2014-11-25mwifiex: add Tx status support for ACTION framesAmitkumar Karwar7-11/+41
ACK status (0/1) for ACTION frames is informed to cfg80211. We will extend existing logic used for EAPOL frames. The cfg80211 API is different here. Also, we need to explicitly free cloned skb.

2014-11-25mwifiex: skip delay main work logic for USB interface.Amitkumar Karwar1-6/+10
We had introduced delay main work logic to avoid processing interrupts when Rx pending packet count reaches high threshold. interrupt processing is restarted later when packet count reduces lower threashold. This helped to reduce unnecessary overhead and improve throughput for SD and PCIe chipsets. As there are no interrupts for USB, we will skip this logic for USB chipsets.

2014-11-24net: wireless: rtlwifi: Do not always include drivers in obj-mAndreas Ruprecht4-12/+0
In four of the rtlwifi drivers, the Makefile contains superfluous statements indicating the compilation of the driver as an LKM regardless of the corresponding Kconfig option. If the corresponding option is set to 'y', the build system will then see the object file in obj-m and obj-y, which leads to a compilation as a built-in only. Even though this leads to the desired behavior, the unconditional appearance in obj-m is confusing for someone reading the Makefile. This patch removes the superfluous Makefile statements.

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

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.

2014-11-24iwlwifi: mvm: use switching_chanctx argument instead of csa_activeLuciano Coelho1-4/+4

2014-11-24iwlwifi: mvm: Handle failed beacon transmissions during CSAAndrei Otcheretianski3-6/+29
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.

We have code to recover and go back to the original channel context if something fails in the middle of switch_vif_chanctx, but we return the error code of the recover calls instead of the original code, so if the recovery succeeds, we will return 0 (success).
