We want to request an interrupt vector for RSS queue per CPU, one vector for fallback queue, and one for non-rx interrupts. Future patch will make sure that no RSS traffic is directed to fallback queue. This will enable us to enable fast path on traffic that otherwise would have been received on the fallback queue.

Currently the code checks if hardware reported both L4 and L3 checksums as valid, and only then reports it as validated to the stack. However, IPv6 does not have checksum at all and the L3 checksum valid bit is always off for IPv6 packets, with the result of the stack re-validating L4 checksum. Fix code to set CHECKSUM_UNNECESSARY also for IPv6 packets whose TCP/UDP checksum was verified.

Use alloc_ordered_workqueue() to allocate the workqueue instead of create_singlethread_workqueue() since the latter is deprecated and is scheduled for removal. There are work items doing related operations that shouldn't be swapped when queued in a certain order hence preserve the strict execution ordering of a single threaded (ST) workqueue by switching to alloc_ordered_workqueue().

Due to hardware bug, upon any shadow free-queue register write access, a legacy RBD shadow register must be written as well. This is required in order to trigger a copy of the shadow registers values after MAC exits sleep state. Specifically, the driver has to write (any value) to the legacy RBD register each time FRBDCB is accessed.

"DQA" is shorthand for "dynamic queue allocation". This enables on-demand allocation of queues per RA/TID rather than statically allocating per vif, thus allowing a potential benefit of various factors. Please refer to the DOC section this patch adds to sta.h to see a more in-depth explanation of this feature. There are many things to take into consideration when working in DQA mode, and this patch is only one in a series. Note that default operation mode is non-DQA mode, unless the FW indicates that it supports DQA mode. This patch enables support of DQA for a station connected to an AP, and works in a non-aggregated mode. When a frame for an unused RA/TID arrives at the driver, it isn't TXed immediately, but deferred first until a suitable queue is first allocated for it, and then TXed by a worker that both allocates the queues and TXes deferred traffic. When a STA is removed, its queues goes back into the queue pools for reuse as needed.

TX CMD API has changed to support offload assist. Currently we do not enable checksum yet, but must set the padding indication, to avoid FW errors. Set other amsdu flag as well.

We insert padding if the MAC header's size is not a multiple of 4 to ensure that the SNAP header is DWORD aligned. When we do so, we let the firmware know by setting a bit in Tx command (TX_CMD_FLG_MH_PAD) which will instruct the firmware to drop those 2 bytes before sending the frame. However, this is not needed for AMSDU as the sub frame header (14B) complements the MAC header (26B) so that the SNAP header is DWORD aligned without adding any pad. Until 9000, the firmware didn't check the TX_CMD_FLG_MH_PAD bit but rather checked the length of the MAC header itself and assumed the entity that enqueued the frame (driver or internal firmware code) added the pad. Since the driver inserted the pad even for AMSDU this logic applied. Note that the padding is a DMA optimization but it's not strictly needed, so we could pad even if it was not needed. However, the CSUM hardware introduced for the 9000 devices requires to not pad AMSDU as it is not needed, and will fail if such a pad exists. Due to older FW not checking the padding bit but checking the mac header size itself - we cannot do this adjustments for older generations. Do not align the size if it is an AMSDU and HW checksum is enabled - which will only happen on 9000 devices and on.

When entering suspend the driver calls iwl_disable_interrupts() and then iwl_pcie_disable_ict(). On resume the driver calls only iwl_pcie_reset_ict() without calling explicitly to iwl_enable_interrupts(). This mostly works since iwl_pcie_reset_ict is calling to iwl_enable_interrupts, but it doesn't work when there is no ict_table in MSIx mode. The result is that driver tries to resume but fails since it doesn't get the RX interrupt from FW indicating that d0i3 exit was completed. Fix it by adding an explicit call to enable interrupts.

LQM stands for Link Quality Measurement. The firmware will collect a defined set of statitics (see the notification for details) that allow to know how busy the medium is. The driver issues a request to the firmware that includes the duration of the measurement (the firmware needs to be on channel for that amount of time) and the timeout (in case the firmware has a lot of offchannel activities). If the timeout elapses, the firmware will send partial results which are still valuable. In case of disassociation / channel switch and alike, the driver is in charge of stopping the measurements and the firmware will reply with partial results. The user space API for now is debugfs only and will be implmemented in an upcoming patch.

Paging contains 3 sections in the fw. The first for the paging separator, The second for the CSS block, the third with the paging data. Currently if the driver finds the paging separator, and there is only section left (CSS), once reading the CSS section, the driver will attempt to read the paging data and will go out of the arrays bounds.

Currently the driver has 2 buffers for paging: 1. paging db - this contains all of the pages that were in the FW image, that the driver stores for the FW. This is allocated for each block separately (not contiguous). 2. download buffer - we need to provide this empty buffer for the iwl_sdio_load_fw_chunk function to copy the requested pages to the shared memory. This is one big buffer of contiguous memory whose size is the size of all the blocks that the fw paging section can contain. This download buffer size is too big, and causes the allocation to fail sometimes. Since the driver allocates memory for each block separately, it is not possible for the FW to request all of the pages in one request (the FW gives an address and size, so blocks need to be contiguous for this to happen), therefore the FW is limited to request only one block. Decrease the size of the paging download buffer to be the size of a paging block.

Pull cgroup updates from Tejun Heo: "cgroup changes for v4.6-rc1. No userland visible behavior changes in this pull request. I'll send out a separate pull request for the addition of cgroup namespace support. - The biggest change is the revamping of cgroup core task migration and controller handling logic. There are quite a few places where controllers and tasks are manipulated. Previously, many of those places implemented custom operations for each specific use case assuming specific starting conditions. While this worked, it makes the code fragile and difficult to follow. The bulk of this pull request restructures these operations so that most related operations are performed through common helpers which implement recursive (subtrees are always processed consistently) and idempotent (they make cgroup hierarchy converge to the target state rather than performing operations assuming specific starting conditions). This makes the code a lot easier to understand, verify and extend. - Implicit controller support is added. This is primarily for using perf_event on the v2 hierarchy so that perf can match cgroup v2 path without requiring the user to do anything special. The kernel portion of perf_event changes is acked but userland changes are still pending review. - cgroup_no_v1= boot parameter added to ease testing cgroup v2 in certain environments. - There is a regression introduced during v4.4 devel cycle where attempts to migrate zombie tasks can mess up internal object management.

bond_get_stats() can be called from rtnetlink (with RTNL held) or from /proc/net/dev seq handler (with RCU held) The logic added in commit 5f0c5f73 ("bonding: make global bonding stats more reliable") kind of assumed only one cpu could run there. If multiple threads are reading /proc/net/dev, stats can be really messed up after a while. A second problem is that some fields are 32bit, so we need to properly handle the wrap around problem.
