1dce924d25 add some definition and driver changes in preparation for
two upcoming features:

semi-transparent mode:
    when a device is opened in this mode, the
    user program will be able to mark slots that must be forwarded
    to the "other" side (i.e. from NIC to host stack, or viceversa),
    and the forwarding will occur automatically at the next netmap syscall.
    This saves the need to open another file descriptor and do
    the forwarding manually.

direct-forwarding mode:
    when operating with a VALE port, the user can specify in the slot
    the actual destination port, overriding the forwarding decision
    made by a lookup of the destination MAC. This can be useful to
    implement packet dispatchers.

No API changes will be introduced.
No new functionality in this patch yet.

a74ebfe59e Fix hangs (exposed by spectral scan activity) in STA mode when the
chip hangs.

* Always do a reset in ath_bmiss_proc(), regardless of whether the
  hardware is "hung" or not.  Specifically, for spectral scan, there's
  likely a whole bunch of potential hangs that we don't (yet) recognise
  in the HAL.  So to avoid staying RX deaf persisting until the station
  disassociates, just do a no-loss reset.

* Set sc_beacons=1 in STA mode.  During a reset, the beacon programming
  isn't done.  (It's likely I need to set sc_syncbeacons during a hang
  reset, but I digress.)  Thus after a reset, there's no beacon timer
  programming to send a BMISS interrupt if beacons aren't heard ..
  thus if the AP disappears, you won't get notified and you'll have to
  reset your interface.

This hasn't yet fixed all of the hangs that I've seen when debugging
spectral scan, but it's certainly reduced the hang frequency and it
should improve general STA stability in very noisy environments.

Tested:

* AR9280, STA mode, spectral scan off/on

61cd9692bb Add a quick work-around if ath_beacon_config() to not die if it's called
when an interface is going down.

Right now it's quite possible (but very unlikely!) that ath_reset()
or similar is called, leading to a beacon config call, in parallel with
the last VAP being destroyed.

This likely should be fixed by making sure the bmiss/bstuck/watchdog
taskqueues are canceled whenever the last VAP is destroyed.

c5239edb98 Implement frame (data) transmission using if_transmit(), rather than
if_start().

This removes the overlapping data path TX from occuring, which
solves quite a number of the potential TX queue races in ath(4).
It doesn't fix the net80211 layer TX queue races and it doesn't
fix the raw TX path yet, but it's an important step towards this.

This hasn't dropped the TX performance in my testing; primarily
because now the TX path can quickly queue frames and continue
along processing.

This involves a few rather deep changes:

* Use the ath_buf as a queue placeholder for now, as we need to be
  able to support queuing a list of mbufs (ie, when transmitting
  fragments) and m_nextpkt can't be used here (because it's what is
  joining the fragments together)

* if_transmit() now simply allocates the ath_buf and queues it to
  a driver TX staging queue.

* TX is now moved into a taskqueue function.

* The TX taskqueue function now dequeues and transmits frames.

* Fragments are handled correctly here - as the current API passes
  the fragment list as one mbuf list (joined with m_nextpkt) through
  to the driver if_transmit().

* For the couple of places where ath_start() may be called (mostly
  from net80211 when starting the VAP up again), just reimplement
  it using the new enqueue and taskqueue methods.

What I don't like (about this work and the TX code in general):

* I'm using the same lock for the staging TX queue management and the
  actual TX.  This isn't required; I'm just being slack.

* I haven't yet moved TX to a separate taskqueue (but the taskqueue is
  created); it's easy enough to do this later if necessary.  I just need
  to make sure it's a higher priority queue, so TX has the same
  behaviour as it used to (where it would preempt existing RX..)

* I need to re-review the TX path a little more and make sure that
  ieee80211_node_*() functions aren't called within the TX lock.
  When queueing, I should just push failed frames into a queue and
  when I'm wrapping up the TX code, unlock the TX lock and
  call ieee80211_node_free() on each.

* It would be nice if I could hold the TX lock for the entire
  TX and TX completion, rather than this release/re-acquire behaviour.
  But that requires that I shuffle around the TX completion code
  to handle actual ath_buf free and net80211 callback/free outside
  of the TX lock.  That's one of my next projects.

* the ic_raw_xmit() path doesn't use this yet - so it still has
  sequencing problems with parallel, overlapping calls to the
  data path.  I'll fix this later.

Tested:

* Hostap - AR9280, AR9220
* STA - AR5212, AR9280, AR5416

e3edca225f Satisfy the intent of kern/151564: [ciss] ciss(4) should increase
CISS_MAX_LOGICAL to 107

Submitter wanted to increase the number of logical disks supported by ciss(4)
by simply raising the CISS_MAX_LOGICAL value even higher.  Instead, consult
the documentation for the raid controller (OPENCISS) and poke the controller
bits to ask it for how many logical/physical disks it can handle.

Revert svn R242089 that raised CISS_MAX_LOGICAL to 64 for all controllers.

For older controllers that don't support this mechanism, fallback to the old
value of 16 logical disks.  Tested on P420, P410, P400 and 6i model ciss(4)
controllers.

This should will be MFC'd back to stable/9 stable/8 and stable/7 after the MFC
period.

87aa6825ff cxgbe/tom: Basic CLIP table management.
This is the Compressed Local IPv6 table on the chip.  To save space, the
chip uses an index into this table instead of a full IPv6 address in
some of its hardware data structures.

For now the driver fills this table with all the local IPv6 addresses
that it sees at the time the table is initialized.  I'll improve this
later so that the table is updated whenever new IPv6 addresses are
configured or existing ones deleted.

  the on-board CP0 interrupt management parts on the MIPS).  If the
  soc bus in a MIPS DTS file is declared as "mips4k,cp0"-compatible,
  then this will be enabled.  This is sufficient to allow IRQs to be

* add a new ioctl to enable/trigger spectral scan at channel change/reset;
* set do_spectral consistently if it's enabled, so a channel set/reset

  are actually received;
* for NICs that don't do spectral scan, don't bother checking the

This change was originally intended to account for test kthreads under

I did not observe any problems with this change, but my testing didn't
exhaust the kinds of corner cases that could cause problems.  It is not
that important to account for these test threads under nvmecontrol, so I

973d40776c Bring over the basic spectral scan framework code from Qualcomm Atheros.
This includes the HAL routines to setup, enable/activate/disable spectral
scan and configure the relevant registers.

This still requires driver interaction to enable spectral scan reporting.
Specifically:

* call ah_spectralConfigure() to configure and enable spectral scan;
* .. there's currently no way to disable spectral scan... that will have
  to follow.
* call ah_spectralStart() to force start a spectral report;
* call ah_spectralStop() to force stop an active spectral report.

The spectral scan results appear as PHY errors (type 0x5 on the AR9280,
same as radar) but with the spectral scan bit set (0x10 in the last byte
of the frame) identifying it as a spectral report rather than a radar
FFT report.

Caveats:

* It's likely quite difficult to run spectral _and_ radar at the same
  time.  Enabling spectral scan disables the radar thresholds but
  leaves radar enabled.  Thus, the driver (for now) needs to ensure
  that only one or the other is enabled.

* .. it needs testing on HT40 mode.

Tested:

* AR9280 in STA mode, HT/20 only

TODO:

* Test on AR9285, AR9287;
* Test in both HT20 and HT40 modes;
* .. all the driver glue.

1a7c3e9097 Regression issue:
Use a boundary of zero, hence a PAGE_SIZE boundary
is implied by all memory allocations.

Background:
Busdma has problems to allocate more than PAGE_SIZE
bytes when the boundary is PAGE_SIZE bytes too.
Initially it was thought that a boundary of PAGE_SIZE
bytes will only affect loading of DMA memory, so that
segments get split correctly, but it also affects
allocation of DMA'able memory.

Solution:
USB can detect big segments and split them as required
by the USB code.
