2014-11-24iwlwifi: mvm: disable PS during channel switchLuciano Coelho
Disable PS when pre_channel_switch is called and add the post_channel_switch operation to re-enable PS when the channel switch is completed. Signed-off-by: Luciano Coelho <luciano.coelho@intel.com>
2014-11-24iwlwifi: mvm: Handle failed beacon transmissions during CSAAndrei Otcheretianski
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.

2014-11-24iwlwifi: mvm: return the actual error code when switch_vif_chanctx failsLuciano Coelho
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). Fix this by not assigning the return value of the recovery calls to ret. Signed-off-by: Luciano Coelho <luciano.coelho@intel.com>
2014-11-24iwlwifi: mvm: add support for CHANCTX_SWMODE_REASSIGN_VIFLuciano Coelho
Add support to reassign vif in switch_vif_chanctx. This is similar to the existing CHANCTX_SWMODE_SWAP_CONTEXTS mode, but doesn't delete the old context nor creates a new one, doing to switch between two existing contexts. Signed-off-by: Luciano Coelho <luciano.coelho@intel.com>

2014-11-24iwlwifi: mvm: only save csa_vif in AP/GO modeLuciano Coelho
We only need the csa_vif in AP/GO modes, and assigning for other interfaces may cause problems, because csa_vif is never cleared. To prevent this, only assign the value if the iftype is NL80211_IFTYPE_AP. Use a switch to do this, even though, for now, only the AP interface type is handled, because soon other interface types will be added as well. Additionally, convert the WARN() in the error case when a channel-switch is already running to WARN_ONCE(). Signed-off-by: Luciano Coelho <luciano.coelho@intel.com>

When switching is initiated by mac80211, use a delayed work to periodically reschedule it from iwlwifi. Give the FW mac80211 generated TDLS channel-switch request/response templates.

2014-11-24iwlwifi: mvm: disconnect TDLS peers on reconfigArik Nemtsov
When TDLS peers are present the FW will send packets on a dedicated TID vs. the peer when performing TDLS channel-switches. The driver configures the TID on connection to the peer and the FW is responsible for maintaining the state of QoS seqno and PN/IV for encryption. If the FW asserts, the driver cannot correctly reconfigure the starting seqno/PN to the reloaded FW, thus forcing us to reconnect the peer.

When we pre-populate the skb->head for the stack, we only pull in the 802.11 header including crypto (assuming the packet isn't short enough to be in there completely.) This is fine, but in ieee80211_data_to_8023() we later unconditionally pull 8 more bytes for the SNAP header and ethertype field (except for mesh or 4-addr, where it's even more, but we don't care as much about them).

2014-11-24iwlwifi: mvm: add WEP RX hardware offload supportJohannes Berg
In the original driver, we decided to not implement WEP RX hardware offload because of a quirk with the firmware API - it allows setting global WEP keys that then get used for all virtual interfaces, which is clearly wrong if more than one exists, and it allows setting per- station keys but then separates multicast and unicast keys. In order to implement WEP RX hardware offload, work around these limitations by uploading each WEP key twice, once as multicast and once as unicast, but point them both to the same key slot (offset) and use the same key material so the slot overwrite on the second upload doesn't actually change anything. Upon removal, also remove the key twice so the station no longer references it. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>

The driver must set the keep alive period regardless of power management state. The keep alive period must be greater or equal to both the NIC's maximum sleep period, and the listen interval. However, we were confusing time units (TU) and msec, so fix that.

2014-11-23iwlwifi: mvm: New skip over dtim policyAvri Altman
Our firmware scheduler suffers from false wake-up on 500 time units. that is if the dtim interval exceeds 500 time units, the fw wakes up, understands that the next wake-up event is still ahead, and if this event is more than 10msec in the future - goes back to sleep, otherwise - stay awake. For example, say that the beacon interval is 101 and the dtim period is 5, the dtim interval is 101 x 5 = 505, and we will stay awake for those extra 5msec. So on the one hand the dtim interval should be congruent to the beacon interval times the dtim period, and on the other should minimize the false wake-ups event. This change applies only to D0/D3 power modes. Signed-off-by: Avri Altman <avri.altman@intel.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
2014-11-23iwlwifi: mvm: move deferred d0i3 exit to resume_complete opEliad Peller
The deferred d0i3 exit is currently implemented in the resume op, which is called when mac80211 starts its resume process. However, mac80211 still doesn't handle frames at this stage, which results in frames being dropped. Move the deferred d0i3 handling to the reconfig_complete callback, in order to make sure mac80211 is fully available at this point.

2014-11-23iwlwifi: mvm: add support for WMM Access ControlEmmanuel Grumbach
After the corresponding mac80211 patch, we can now report the airtime used for each transmitted packet and mac80211 will be able to implement WMM-AC with that information. To support WMM-AC in the driver then, report the airtime and advertise support. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
2014-11-23iwlwifi: change max HT and VHT A-MPDU exponentEran Harary
Add two new parameters to iwl_cfg: max_ht_ampdu_exponent and max_vht_ampdu_exponent. These parameters, if set, will set new values to the maximum of HT and VHT A-MPDU exponent for the A-MPDU length exponent.

2014-11-23iwlwifi: mvm: Insert DS Parameter Set placeholder in probesAndrei Otcheretianski
Since it's too complicated for the fw to insert a DS Parameter Set element in the middle of the frame, it was decided that it should be done by the host. The fw will only parse the frame and update the current channel field.
