Last EBS status wasn't set to success in the initialization, which caused the first scan to be without EBS. Fix that. When EBS is not enabled by the driver, the FW still sends ebs_status success, which can override EBS failure state. Consider only EBS failures, to avoid such override. Last_ebs_success is set back to true upon disconnection. Last_ebs_success wasn't set in umac scan abort flow, fix that too. Signed-off-by:

Different queue can have different behavior. While it can be unacceptable for a certain queue to be stuck for 2 seconds (e.g. the command queue), it can happen that another queue will stay stuck for even longer (a queue servicing a power saving client in GO). The op_mode can even make the timeout be a function of the listen interval. Reviewed-by:

This watchdog allows to monitor the transmit queues. When a queue doesn't progress for a too long time, a timer fires and then, debug data can be collected. This watchdog has never been enabled on dvm controlled devices, so don't enable it there. In order to have it running on mvm controlled devices, we need to fix a small issue in the transport layer: mvm controlled devices use the shadow registers optimization. In this case, the watchdog wasn't running at all, even if enabled by the module parameter. Fix that on the way. Reviewed-by:

During out-of-channel activities (e.g. scan) TDLS ch-switch responses from a peer are kept in FW. These packets arrive only after the out-of-channel activity is complete, which can be in the order of several seconds. Since TDLS ch-sw has no dialog-token-like mechanism for distinguishing sessions, use the GP2 time of the incoming ch-switch response to discern validity. For this purpose record the GP2 time of an outgoing TDLS ch-sw request and compare to the Rx time of the ch-sw response. The methods works in practice since the GP2 time of FW-deferred Rx is accurate and contains the real Rx timestamp. Signed-off-by:

Add a response-received state and add more limits on allowed requests in each state of the connection. Previously ch-switch requests from other peers could interrupt an outgoing active ch-switch. Also stale packets from the current peer could disrupt the channel switch state. Signed-off-by:

The base address of the scheduler in the device's memory (SRAM) comes from two different sources. The periphery register and the alive notification from the firmware. We have a check in iwl_pcie_tx_start that ensures that they are the same. When we resume from WoWLAN, the firmware may have crashed for whatever reason. In that case, the whole device may be reset which means that the periphery register will hold a meaningless value. When we come to compare trans_pcie->scd_base_addr (which really holds the value we had when we loaded the WoWLAN firmware upon suspend) and the current value of the register, we don't see a match unsurprisingly. Trick the check to avoid a loud yet harmless WARN. Note that when the WoWLAN has crashed, we will see that in iwl_trans_pcie_d3_resume which will let the op_mode know. Once the op_mode is informed that the WowLAN firmware has crashed, it can't do much besides resetting the whole device. CC: <stable@vger.kernel.org> Reviewed-by:

Some devices have 31 TFD queues. Don't enable it yet since there are still issues with it, but at least prepare the code for it. There was a bug in the read pointer assignment, fix that. Also, move the inline functions to iwl-scd.h which is the right place. Reviewed-by:

VHT Beamformer (BFER) will be used if the peer supports it and there's a benefit to use it vs. STBC or SISO. The driver now tells the FW whether BFER and/or STBC are allowed but the FW will make the decision to use either or stick to SISO on its own. BFER is limited to a single remote peer. The driver takes care of ensuring this to the FW and prioritizes with which peer BFER will be used. Signed-off-by:

We don't really need to use different mac colors when adding mac contexts, because they're not used anywhere. In fact, the firmware doesn't accept 255 as a valid color, so we get into a SYSASSERT 0x3401 when we reach that. Remove the color increment to use always zero and avoid reaching 255.

In the PHY_CTXT command sent to the FW the TX chains were indeed configured by the values of both FW TLVs and of NVM, but the RX chains were left out and configured only by FW TLV. This causes problems in 4165 HW, where there are 1x1 antennas, and the wrong configuration denies the driver from connecting to the AP. Signed-off-by:

The driver loads the 2 CPU sections, then it needs to let the firmware know to start the authentication of the sections. This is done by writing the relevants bits to FH_UCODE_LOAD_STATUS. For CPU1, the driver sets the lower 16 bits. For both CPUs, the driver sets all the 32 bits. Signed-off-by:
