Instead of having: iwl_pcie_irq_handler iwl_pcie_isr_ict iwl_pcie_isr_non_ict we now have: iwl_pcie_irq_handler: if (use_ict)) iwl_pcie_int_cause_ict; else iwl_pcie_int_cause_non_ict; This is much clearer. Signed-off-by:Emmanuel Grumbach <emmanuel.grumbach@intel.com>

We now disable the interrupts in the hardware from the upper half and all the rest (including reading the interrupt cause) is done in the handler. Reviewed-by:

The purpose of this is to be able to call these functions from the interrupt handler and not from the primary interrupt handler. Reviewed-by:

Separate the code that simply disables interrupt in the hardware and the code that checks what interrupt fired. This will be useful to move the second part in the threaded handler which will be done in a future patch. Reviewed-by:

Track the interrupt mask in software, making it exactly what is configured in the interrupt mask register in the hardware. This allows not to access the register from the interrupt handler. This was the case for ICT interrupt already, but not for non-ICT interrupt. Reviewed-by:

Since iwl_trans_pcie_alloc_ict is called in the PCIe allocation code, we always set CSR_INT_BIT_RX_PERIODIC. Move that bit to the default list of interrupts we enable and simplify the code. Also use dma_zalloc_ and avoid to memset the memory afterwards. trans_pcie->ict_index is 0 since trans_pcie has just been kzalloced, remove the redundant assignment. Reviewed-by:

RTS protection was turned on once aggregation was enabled but it was never turned off. Remove turning on RTS protection in the LQ command completely as TX_CMD_FLG_PROT_REQUIRE gets set in iwl_mvm_set_tx_cmd for every Tx which is part of an aggregation. This would already cause RTS protection to be used during aggregations. Signed-off-by:

MCS9 introduces some corner cases in the current rs algorithm which may lead to non optimal throughput and instability in the throughput. Until all the corner cases are resolved disable MCS9 for Tx as a workaround which yields better throughput results as MCS8 is much more stable. Signed-off-by:

Fix a regression introduced in "iwlwifi: mvm: fix ht protection flags" where an AP/IBSS MAC context could have been updated even before the context was added to the FW.

The logs are emitted in a flow in which there were retries and the rates in the rate table entry didn't match the active or search table. This doesn't indicate a problem and is expected in most cases where there will be retries for some reason. Remove the logs. Signed-off-by:

The new logic will attempt more rates with less retries per rate. Also when starting off with MIMO it will fallback to SISO with the same MCS and only then to Legacy. Previously we fell back directly to Legacy. Signed-off-by:

Simplify the code a bit more by extracting the rates table building logic into a separate function and handle setting a fixed rate for debug in a separate flow. Also avoid using and saving ucode rate format in different places. Instead use rs_rate struct and convert to ucode format only when filling the rates table in the LQ command. Signed-off-by:

In case a sync command timeouts or Tx is stuck while a FW error interrupt arrives, we might call iwl_op_mode_nic_error twice before a restart has been initiated. This will cause a reprobe. Unify calls to this function at the transport level and only call it on the first FW error in a given by checking the transport FW error flag. While at it, remove the privately defined iwl_nic_error from PCIE code and use the common callback instead. Signed-off-by:

The stop_hw trans callback is not well defined. It is missing in many cleanup flows and the division of labor between stop_device/stop_hw is cumbersome. Remove stop_hw and use stop_device to perform both. Implement this for all current transports. PCIE needs some extra configuration the op-mode is leaving to configure RF kill. Expose this explicitly as a new op_mode_leave trans callback. Take the call to stop_device outside iwl_run_mvm_init_ucode, this makes more sense and WARN when we want to run the INIT firmware while it has run already. Signed-off-by:

FW still does not support power management on multiple MAC interfaces. Currently the driver enforce this limitation by disabling PM if second interface is added. Change this behavior to allow PM on a single interface even if other interfaces exist but not bound to any specific PHY. PM will be enabled if only one single interface is bound. Signed-off-by:

FW implements protective algorithm to identify AP's improper uAPSD behavior. FW sends misbehaving AP notification in this case. Add this notification handling. Avoid using uAPSD in next association to the exactly same AP. Refactor iwl_mvm_power_build_cmd() to move uAPSD related code to a separate function. Signed-off-by:

If the device is MIMO and VHT capable it supports Tx STBC. Unlike HT, any chip that supports VHT also support STBC so no need for a config parameter. Using num_of_ants multiple times warranted caching it. Signed-off-by:

It was set to zero which reflects support of a single STS. Set according to the number of Rx antennas which correctly reflects the number of STSs the STA can receive in a VHT NDP. This improves beamforming and has been tested to improve Rx throughput. Signed-off-by:

Not all chips support STBC so allow this to be another config parameter per chip type. If STBC is supported then publish it in the HT caps. Since 7260/7265/3160 chips support it - set the stbc support bit. Signed-off-by:

This patch adds a cipher scheme support to extend a set of the supported ciphers. The driver reads a cipher scheme list TLV from FW image and passes it to mac80211 on hw registration. After the cipher schemes are registered the driver handles key installation and Tx/Rx calls related to the new ciphers. Signed-off-by:
