2014-11-24iwlwifi: mvm: use private TFD queues for TDLS stationsArik Nemtsov
When adding a TDLS station, allocate 4 new queues for it. Configure them to FW and enable them. On station removal, drain the queues if needed and disable them when empty. Make sure to flush all packets in the private queues of TDLS stations in the mac80211 flush() callback.

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.

2014-11-24iwlwifi: mvm: pull SNAP header into skb->headJohannes Berg
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). Avoid the additional later pull by pulling in those 8 bytes here.

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>

2014-11-23iwlwifi: pcie: properly reset the deviceEmmanuel Grumbach
We were toggling the wrong bit when we reset the device, fix that. Moreover, since the reset can take time, we need to wait before we set the rfkill interrupt. Not doing so can be racy since the driver is enabling the rfkill interrupt while the device is resetting which will clear all the registers including the CSR_INT_MASK. This can basically lead to a situation where we don't enable the rfkill interrupt. If that happens, the user will not be able to re-enable the device when de-asserting rfkill.

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.
