| * | | iwlwifi: mvm: document passing unexpected Block Ack Request framesJohannes Berg2016-09-191-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we get an unexpected Block Ack Request frame, the BAID from the hardware will be invalid, and we'll pass it to mac80211 for further handling (sending a delBA action frame.) Add a comment explaining that, in case anyone looks in the future. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>

| * | | iwlwifi: mvm: fix DQA AP mode station assumptionSara Sharon2016-09-191-7/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There was recently a Full AP mode feature added where hostap adds the station at auth stage, and not assoc. However, when running with legacy hostapd, we get the auth response before station was added, and tx_skb_non_sta fails to allocate a queue, resulting in a complete failure of association. Take care of this situation as well. Add a warning when no valid queue is returned at all and make mvm drop the packet instead of passing it on. Refactor the function a bit while at it.

However, there may be cases this ownership needs to be changed. For example, in the following scenario: 1. TID x is owner of a queue 2. Due to a shortage of queues, TID y and z share with x 3. TID x becomes inactive and needs to be removed from the shared queue. In this scenario, if another queue is freed and traffic on x continues, we can't allocate it a new queue as long as it is the owner of the first queue.

| | * | iwlwifi: mvm: support v4 of the TX power commandLuca Coelho2016-07-063-13/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for the v4 version of the TX power command. Just add a new version and do the same sizing tricks that were done when support for v3 was introduced. This patch doesn't support the new functionality introduced, but makes the driver work with the new size of the command.

| | * | iwlwifi: decouple PCIe transport from mac80211Johannes Berg2016-07-061-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The PCIe transport needs to store two pointers in each TX SKB, and currently assumes mac80211's ieee80211_tx_info is present in the CB to do that. In order to remove that assumption, have the opmodes pass in the offset to where the pointers can be stored in the CB and use the offset in the PCIe code. To make the disentanglement complete, remove mac80211.h includes from everywhere in the generic iwlwifi code. This required adding an include of cfg80211.h in one place.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to reduce reliance on mac80211 structs in the core iwlwifi code, store the cipher schemes in the format given by the firmware and convert it later, rather than storing it in the mac80211 format.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Restart flow zeroes the rx_ba_sessions counter. Mac80211 asks driver to tear down of the session only afterwards, and as a result driver didn't free the data. Fix it.

Make sure that this queue is redirected to the lowest AC when adding a new RA/TID to an existing queue. If it isn't - redirect the queue. Also, as redirection revealed a bug in the marking of a shared queue, this patch contains a small fix to make sure a shared queue maintains the appropriate "shared queue marking".

| | * | iwlwifi: mvm: support tdls in dqa modeLiad Kaufman2016-07-062-13/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Support TDLS when working in DQA mode. This is done mainly by NOT doing any special things for TDLS, as the queues are dynamically created anyway, so no need to allocate them ahead of time.
