The masks were wrong. They should be 0xffffffff when SCO, HID or SNIFF profiles are used. They should be 0xffff0000 in any other case (default) to get a bit more throughput when the BT profile allows for it. Fix a debug print on the way. Signed-off-by:

In AP mode, don't attempt to program GTKs into the device, they're used for TX only so not needed and programming them causes error messages. Also, in this case and if key programming fails, avoid trying to remove the key that isn't present later. Reviewed-by:

Fix a bug in writing to indirect (periphery) registers; although writes seem successful the data is not written to the desired address). Also fix address mask for HBUS_TARG_PRPH_RADDR and HBUS_TARG_PRPH_WADDR registers. Signed-off-by:

This allows to test fw restart flow. The hook in transport layer doesn't really make the fw assert. Moving this hook to the op_mode allows to use the fw API to actually send a host command that will make the fw assert. Change the restart_fw module parameter to be a boolean on the way.

The firmware tells the driver to what MACs the received frame belongs (based on the time slot in which it was received). Note that there can be several MACs if they share the same binding. Signed-off-by:

When BT traffic load gets higher, we want to avoid using the shared antenna. In order to do so, we need to tell the AP that we don't support MIMO any more, or at least not all the time: in short, use the SMPS to achieve this. Signed-off-by:

The BT-Coex notification is sent by the fw when there are updates wrt. BT activity. Driver action might be taken based on the info in this notification. For now, update the Ack/Cts_kill_msk if HID / SCO / A2DP profiles are active. Signed-off-by:

Now that we have two drivers (DVM and MVM) stop selecting the DVM one (but make it default) and allow enabling only the MVM driver if so desired. Add a warning for the case of having neither DVM nor MVM enabled -- that's useless. Reviewed-by:

When modifying a MAC, we update its beacon system time which is taken as a base to calculate TBTT. The firmware doesn't use the new timestamp because the time is never used after the MAC and broadcast station were added, but it is safer to not rely on this and avoids the overhead of reading the register every time the MAC is updated.

Newer devices can work on different buses. This means that their configuration can be shared between different buses. Hence the configuration structures should exported to all the buses and not only to PCIE. Change this. Note that this requires all the fields to be the same amongst the buses. If differences will appear, we can always define a part that is bus dependent. Today, this is not needed. Signed-off-by:

Update the NVM parsing functions to add VHT capabilities; they are only added for 5 GHz, of course. This assumes that all devices with NVM reading (rather than EEPROM) that support 5 GHz have VHT, which is true right now. Signed-off-by:

When a station is added, we need to tell the firmware what the SMPS settings and number of streams are. After having the initial data, the firmware will track future changes by itself. Reviewed-by:

With remote wake, the firmware creates a TCP connection and sends some configurable data on it, until a special TCP data packet from the server is received that triggers a wakeup. The configuration is a bit tricky because it is based on packet pattern matching but this is hidden in the driver and the exposed API in cfg80211 is just based on the required TCP connection parameters.

All hardware after 4965 supports this. It's likely that it wasn't set because for 4965 it was irrelevant (HT is only supported on 5 GHz there) and then never updated. Reviewed-by:

mac80211 tells us when we need to dump the frames from the AGG queue instead of releasing them as single MPDUs. Being able to differentiate between the different cases (IEEE80211_AMPDU_TX_STOP_*) allows us to handle races better. When the station is removed, mac80211 asks to flush and removes the station right away. This allows to avoid a case where we still have frames in AGG queues, but the station has been remove already. Note that we can have frames on the shared queues, but this is not a problem: the station in the fw will be kept until all the frames on the shared queues have been drained. AGG queues are a special case since they are dynamically allocated. Signed-off-by:

There's a bug that causes the rate scaling to get stuck when it has to use single-stream rates with a peer that can do GF and SGI; the two are incompatible so we can't use them together, but that causes the algorithm to not work at all, it always rejects updates. Disable greenfield for now to prevent that problem. The MVM driver currently only works on devices that don't support greenfield anyway, but better be safe and not allow us to forget about this.

When we stop an AGG session, we need to look at the sequence numbers in in the private area of the ieee80211_sta struct. This allows us to know is the queue is empty. To get access to this private area, we use fw_id_to_mac_id that maps sta_id (index of the STA in fw table) to ieee80211_sta. When the STA exists in fw, but not in mac80211, we set an ERR ptr in fw_id_to_mac_id. But if we first set an ERR ptr to fw_id_to_mac_id, and only then flush the queues, then we won't be able to access the sequence numbers in ieee80211_sta from the reclaim flow. This means that we will never be able to release an AGG queue when a station is deleted. So first, flush the queue. That will let the reclaim flow call iwl_mvm_check_ratid_empty which will disable the AGG queue as needed, and only then, remove the mapping in fw_id_to_mac_id. Signed-off-by:

This flow happens when we get a failed single Tx response on an AMPDU queue. In this case, the frame won't be sent any more. So we need to move the window on the recipient side. This is done by a BAR. Now if we are in the following case: 10, 12 and 13 are ACKed and 11 isn't. 10 11 12 13. V X V V Then, 11 will be sent 16 times as an MPDU (as oppsed to A-MPDU). If this failed, we are entering the flow described above. So we need to send a BAR with ssn = 12. But in this case, the scheduler will tell us to free frames up to 13 (included). So, it is perfectly possible to get a failed single Tx response on an AMPDU queue that makes the scheduler's ssn jump by more than 1 single packet. Signed-off-by:

Since the device is being restarted, all the Rx / Tx Block Ack sessions are been wiped out by the driver. So ignore the requests from mac80211 that stops Tx agg while reconfiguring the device. Note that stopping a non-existing Rx BA session is harmless, so just honor mac80211's request. Signed-off-by:
