Gscan is a scan feature which is supported on certain devices only, hence the need for a TLV flag for it. For devices that support gscan store the gscan capabilities advertised by the FW so the driver can report it to upper layers.

Our firmware scheduler used to suffer from false wake-up on 500 time units. We had to came up with a formula to address this buggy behavior. Now that our firmware is fixed, we can go back to our old policy. Signed-off-by: Avri Altman <avri.altman@intel.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>

Family 8000 products has 2 embedded processors, the first known as LMAC (lower MAC) and implements the functionality from previous products, the second one is known as UMAC (upper MAC) and is used mainly for driver offloads as well as new features. The UMAC is typically “less” real-time than the LMAC and is used for higher level controls. The UMAC's code/data size is estimated to be in the mega-byte arena, taking into account the code it needs to replace in the driver and the set of new features. In order to allow the UMAC to execute code that is bigger than its code memory, we allow the UMAC embedded processor to page out code pages on DRAM. When the device is master on the bus(PCI) the driver saves the UMAC's image pages in blocks of 32K in the DRAM and sends the layout of the pages to the FW. The FW can load / unload the pages on its own. The driver can support up to 1 MB of pages. Add paging mechanism for the UMAC on PCI in order to allow the program to use a larger virtual space while using less physical memory on the device.

Move the TX PN assignment (for CCMP only) to the driver. This prepares the driver for future DSO (driver segmentation offload) where it will split an SKB into multiple MPDUs by itself. For TDLS, split out the CCMP TX command handling so that it won't get a PN assigned, the firmware assigns the PN in that case.

Since the CSR_DRAM_INIT_TBL_WRITE_POINTER bit wasn't set on ict reset, in some flows (like disable ict followed by immediate reset ict) the driver and hardware went out of sync (the driver cleared the ict_index, while the hw kept it intact). Fix it by setting the flag when resetting ict. Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>

Some CSR registers have to be configured also in case of suspend/resume with unified image (which doesn't includes reconfiguration flow). Reuse the existing d3_suspend/d3_resume trans ops, while making sure some configurations are a bit different, according to the wowlan type. After this change, we no longer need the special wowlan_d0i3 configurations done in iwl_pci_resume, as they are already being done in the d3_resume op.

TCP software implementation on the host requires extensive computing power. Offloading even some of the TCP/IP stack to the NIC might save a significant overhead. In order to enable this feature on our hw, we need to configure it first. Once done, we mark this capability, to be advertised later to the OS via ieee80211_register_hw. The driver Rx indications for TCP Checksum is integrated within the standard Rx status. The driver responds to those indications as follows: If the frame was tested by hw and checksum ok report CHECKSUM_UNNECESSARY. Otherwise, report CHECKSUM_NONE.

The firmware debug infrastructure allows the user to provide a firmware that will toggle a few registers to configure the debugging capabilities. On certain devices, certain operations are forbidden. Executing a forbidden operation will cause the hardware to die in a way that only driver unload / load will bring it back to life. Fortunately, there is a way to know in advance if those operations will be accepted by the device. This is where the new PRPH_BLOCKBIT operation plays its role. If the bit X from PRPH register Y is set, then we should prevent any further register configuration. When that happens, drop a line in the kernel log since this is really an error state: the user won't have his device configured as he expected. Add operations that will be used in the future: INDIRECT_ASSIGN, INDIRECT_SETBIT, and INDIRECT_CLEARBIT. Other debugging configurations (such as destination configuration for the monitor) will take place in any case.

In iwl_mvm_tx_skb_non_sta(), in case of managed interface, use the AP station for multicast frames instead of the auxiliary station as otherwise the frames can be sent to an absent P2P GO as the FW does not block transmissions for the auxiliary station since it is not associated with the station MAC context. Note that this is not possible for unicast frames, as a TDLS discovery response is sent without a station entry, and in this case the P2P GO NoA should not block transmission to the peer.

This reverts commit 088070a2. When working in d0i3_on_idle mode, we explicitly go out of d0i3 on resume (so other potential commands could be sent). However, D0I3_DEFER_WAKEUP is currently cleared on resume complete (which happens only later on), causing d0i3 exit to timeout. Since mac80211 was modified to accept incoming frames once drv_resume was called, we can safely revert this patch, and handle the pending work on iwl_mvm_resume().

Existing UMAC commands already use the long header, but are sent with group 0 and the long header inserted manually. Move them to the group 1 to take advantage of the header building in the low- level transport. Existing firmware ignores the group_id field (it's reserved) and the first firmware that really supports long command headers can parse all commands in both group 0 (with short header) and group 1 (with long header.)

As the firmware is slowly running out of command IDs and grouping of commands is desirable anyway, the firmware is extending the command header from 4 bytes to 8 bytes to introduce a group (in place of the former flags field, since that's always 0 on commands and thus can be easily used to distinguish between the two. In order to support this most easily in the driver widen the command command ID used in the command sending functions and encode the new values (group and version) in the ID. That way existing code doesn't have to be changed (since the higher bits are 0 automatically) and newer code can easily use the new ID generation function to create a value to use in place of just the command ID.

The 'flags' field really has been reserved in the firmware API for a very long time, probably since 4965. As a consequence, the field is always 0 and checking for a IWL_CMD_FAILED_MSK flag makes no sense. Rename the field to 'reserved', get rid of IWL_CMD_FAILED_MSK and all the code for it.

In iwlmvm firmwares, the Byte count written in the scheduler byte count table is in DWORDs and not in bytes. We should check that this value fits in the 12 bits and the value can be either in bits of in DWORD or bytes depending on the firmware.

This driver currently has some very confusing ADD_STA response handling that runs asynchronously in the background for all of the commands, but is only really necessary for synchronous ones (the really asynchronous ones can only be done for already existing stations), and for the sync ones it actually waits for the RX handler to return a status code. Rework this to keep the debug printing in the handler, but do the code that's supposed to have an effect only for sync commands in the command sending function.

The current key offset assignment algorithm always uses the lowest unused key offset, which will potentially lead to issues when the firmware will change to take the key material for TX from the key table rather than from the TX command. In order to avoid those issues (and avoid forgetting about them) change the key offset allocation algorithm now to avoid reusing key offsets quickly. The new algorithm always picks as the next offset the least recently freed offset, i.e. the offset that has been unused for the longest amount of time. This is implemented by having a generation counter for each key offset that is incremented every time a key is deleted, except for the one that's deleted, which is reset to zero. Thus the highest counter is the key that's been unused longest. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>

During NIC initialization shared HW is reset and this disables the scheduler. Some HW platforms do not activate the scheduler after it. Consequently all HCMD sent by the driver stay at the queues which cause to queue stuck. Set the scheduler to work on auto active mode so it would be activated upon change over one of the queues' write pointer.
