Rui Paulo d4886179cb Import OpenBSD's iwm WiFi driver for Intel 3160/7260/7265. 
There are still several bugs, but I've been using it for a while now.
Thanks to all the testers and to Adrian for his help with this
driver.

This driver isn't connected to the build yet, but it will be soon.

There's no MFC planned because the driver isn't very stable yet.

Tested by:	adrian, gjb, dumbbell (others that I forgot).

* CSR (control and status registers)

* CSR registers are mapped directly into PCI bus space, and are accessible

* low power states due to driver-invoked device resets
* (e.g. IWM_CSR_RESET_REG_FLAG_SW_RESET) or uCode-driven power-saving modes.

* Use iwl_write32() and iwl_read32() family to access these registers;
* these provide simple PCI bus access, without waking up the MAC.
* Do not use iwl_write_direct32() family for these registers;
* no need to "grab nic access" via IWM_CSR_GP_CNTRL_REG_FLAG_MAC_ACCESS_REQ.
* The MAC (uCode processor, etc.) does not need to be powered up for accessing

/**
* Tx Scheduler
*
* The Tx Scheduler selects the next frame to be transmitted, choosing TFDs
* (Transmit Frame Descriptors) from up to 16 circular Tx queues resident in
* host DRAM. It steers each frame's Tx command (which contains the frame
* data) into one of up to 7 prioritized Tx DMA FIFO channels within the
* device. A queue maps to only one (selectable by driver) Tx DMA channel,
* but one DMA channel may take input from several queues.
*
* Tx DMA FIFOs have dedicated purposes.
*
* For 5000 series and up, they are used differently
* (cf. iwl5000_default_queue_to_tx_fifo in iwl-5000.c):
*
* 0 -- EDCA BK (background) frames, lowest priority
* 1 -- EDCA BE (best effort) frames, normal priority
* 2 -- EDCA VI (video) frames, higher priority
* 3 -- EDCA VO (voice) and management frames, highest priority
* 4 -- unused
* 5 -- unused
* 6 -- unused
* 7 -- Commands
*
* Driver should normally map queues 0-6 to Tx DMA/FIFO channels 0-6.
* In addition, driver can map the remaining queues to Tx DMA/FIFO
* channels 0-3 to support 11n aggregation via EDCA DMA channels.
*
* The driver sets up each queue to work in one of two modes:
*
* 1) Scheduler-Ack, in which the scheduler automatically supports a
* block-ack (BA) window of up to 64 TFDs. In this mode, each queue
* contains TFDs for a unique combination of Recipient Address (RA)
* and Traffic Identifier (TID), that is, traffic of a given
* Quality-Of-Service (QOS) priority, destined for a single station.
*
* In scheduler-ack mode, the scheduler keeps track of the Tx status of
* each frame within the BA window, including whether it's been transmitted,
* and whether it's been acknowledged by the receiving station. The device
* automatically processes block-acks received from the receiving STA,
* and reschedules un-acked frames to be retransmitted (successful
* Tx completion may end up being out-of-order).
*
* The driver must maintain the queue's Byte Count table in host DRAM
* for this mode.
* This mode does not support fragmentation.
*
* 2) FIFO (a.k.a. non-Scheduler-ACK), in which each TFD is processed in order.
* The device may automatically retry Tx, but will retry only one frame
* at a time, until receiving ACK from receiving station, or reaching
* retry limit and giving up.
*
* The command queue (#4/#9) must use this mode!
* This mode does not require use of the Byte Count table in host DRAM.
*
* Driver controls scheduler operation via 3 means:
* 1) Scheduler registers
* 2) Shared scheduler data base in internal SRAM
* 3) Shared data in host DRAM
*
* Initialization:
*
* When loading, driver should allocate memory for:
* 1) 16 TFD circular buffers, each with space for (typically) 256 TFDs.
* 2) 16 Byte Count circular buffers in 16 KBytes contiguous memory
* (1024 bytes for each queue).
*
* After receiving "Alive" response from uCode, driver must initialize
* the scheduler (especially for queue #4/#9, the command queue, otherwise
* the driver can't issue commands!):

/**
* Rx SRAM Control and Status Registers (RSCSR)
*
* These registers provide handshake between driver and device for the Rx queue
* (this queue handles *all* command responses, notifications, Rx data, etc.
* sent from uCode to host driver). Unlike Tx, there is only one Rx
* queue, and only one Rx DMA/FIFO channel. Also unlike Tx, which can
* concatenate up to 20 DRAM buffers to form a Tx frame, each Receive Buffer
* Descriptor (RBD) points to only one Rx Buffer (RB); there is a 1:1
* mapping between RBDs and RBs.
*
* Driver must allocate host DRAM memory for the following, and set the
* physical address of each into device registers:
*
* 1) Receive Buffer Descriptor (RBD) circular buffer (CB), typically with 256
* entries (although any power of 2, up to 4096, is selectable by driver).
* Each entry (1 dword) points to a receive buffer (RB) of consistent size
* (typically 4K, although 8K or 16K are also selectable by driver).
* Driver sets up RB size and number of RBDs in the CB via Rx config
* register IWM_FH_MEM_RCSR_CHNL0_CONFIG_REG.
*
* Bit fields within one RBD:
* 27-0: Receive Buffer physical address bits [35:8], 256-byte aligned
*
* Driver sets physical address [35:8] of base of RBD circular buffer
* into IWM_FH_RSCSR_CHNL0_RBDCB_BASE_REG [27:0].
*
* 2) Rx status buffer, 8 bytes, in which uCode indicates which Rx Buffers
* (RBs) have been filled, via a "write pointer", actually the index of
* the RB's corresponding RBD within the circular buffer. Driver sets
* physical address [35:4] into IWM_FH_RSCSR_CHNL0_STTS_WPTR_REG [31:0].
*
* Bit fields in lower dword of Rx status buffer (upper dword not used
* by driver:
* 31-12: Not used by driver
* 11- 0: Index of last filled Rx buffer descriptor
* (device writes, driver reads this value)
*
* As the driver prepares Receive Buffers (RBs) for device to fill, driver must
* enter pointers to these RBs into contiguous RBD circular buffer entries,
* and update the device's "write" index register,
* IWM_FH_RSCSR_CHNL0_RBDCB_WPTR_REG.
*
* This "write" index corresponds to the *next* RBD that the driver will make
* available, i.e. one RBD past the tail of the ready-to-fill RBDs within
* the circular buffer. This value should initially be 0 (before preparing any
* RBs), should be 8 after preparing the first 8 RBs (for example), and must
* wrap back to 0 at the end of the circular buffer (but don't wrap before
* "read" index has advanced past 1! See below).
* NOTE: DEVICE EXPECTS THE WRITE INDEX TO BE INCREMENTED IN MULTIPLES OF 8.
*
* As the device fills RBs (referenced from contiguous RBDs within the circular
* buffer), it updates the Rx status buffer in host DRAM, 2) described above,
* to tell the driver the index of the latest filled RBD. The driver must
* read this "read" index from DRAM after receiving an Rx interrupt from device
*
* The driver must also internally keep track of a third index, which is the
* next RBD to process. When receiving an Rx interrupt, driver should process
* all filled but unprocessed RBs up to, but not including, the RB
* corresponding to the "read" index. For example, if "read" index becomes "1",
* driver may process the RB pointed to by RBD 0. Depending on volume of
* traffic, there may be many RBs to process.
*
* If read index == write index, device thinks there is no room to put new data.
* Due to this, the maximum number of filled RBs is 255, instead of 256. To
* be safe, make sure that there is a gap of at least 2 RBDs between "write"
* and "read" indexes; that is, make sure that there are no more than 254
* buffers waiting to be filled.
