f28a552089 Migrate the TX sending code out from under the ath0 taskq and into
the separate ath0 TX taskq.

Whilst here, make sure that the TX software scheduler is also
running out of the TX task, rather than the ath0 taskqueue.

Make sure that the tx taskqueue is blocked/unblocked as necessary.

This allows for a little more parallelism on multi-core machines,
as well as (eventually) supporting a higher task priority for TX
tasks, allowing said TX task to preempt an already running RX or
TX completion task.

Tested:

* AR5416, AR9280 hostap and STA modes

d7acafa1e3 - Improve some comments.
- Make bge_lookup_{rev,vendor}() static.
- Factor out chip identification rather than duplicating the code.
- Sanitize bge_probe() a bit (don't hardcode buffer sizes, allow
  bge_lookup_vendor() to return NULL so the excessive panic() three
  can be removed there, etc.) and return BUS_PROBE_DEFAULT rather than
  hardcoding 0.
- According to the Linux tg3 driver, BCM57791 and BCM57795 aren't
  capable of Gigabit Ethernet.
- Check the return value of taskqueue_start_threads().

4364ec0852 Move lle_event to if_llatbl.h
lle_event replaced arp_update_event after the ARP rewrite and ended up
in if_ether.h simply because arp_update_event used to be there too.
IPv6 neighbor discovery is going to grow lle_event support and this is a
good time to move it to if_llatbl.h.

The two in-tree consumers of this event - OFED and toecore - are not
affected.

7c2fdcac02 - Check the return value of taskqueue_start_threads().
- At least the Saturn chips of 501-6738 cards need a delay after freezing
  the external GMII pins before the internal PHY is accessible again. So
  wait a bit after (un)freezing these. Also don't touch the other bits of

718c2b5b11 Revert the part of r239864 which removed obtaining the SMP mutex around
reading registers from other CPUs. As it turns out, the hardware doesn't
really like concurrent IPI'ing causing adverse effects. Also the thought
deadlock when using this spin lock here and the targeted CPU(s) are also
holding or in case of nested locks can't actually happen. This is due to
the fact that on sparc64, spinlock_enter() only raises the PIL but doesn't
disable interrupts completely. Thus direct cross calls as used for the
register reading (and all other MD IPI needs) still will be executed by
the targeted CPU(s) in that case.

091fd0ab54 Add support for transparent mode while in netmap.
By setting dev.netmap.fwd=1 (or enabling the feature with a per-ring flag),
packets are forwarded between the NIC and the host stack unless the
netmap client clears the NS_FORWARD flag on the individual descriptors.

This feature greatly simplifies applications where some traffic
(think of ARP, control traffic, ssh sessions...) must be processed
by the host stack, whereas the bulk is handled by the netmap process
which simply (un)marks packets that should not be forwarded.
The default is chosen so that now a netmap receiver operates
in a mode very similar to bpf.

Of course there is no free lunch: traffic to/from the host stack
still operates at OS speed (or less, as there is one extra copy in
one direction).
HOWEVER, since traffic goes to the user process before being
reinjected, and reinjection occurs in a user context, you get some
form of livelock protection for free.

1d04725a7a ext2fs: make some inode fields match the ext2 spec.
Ext2fs uses unsigned fields in its dinode struct.
FreeBSD can have negative values in some of those
fields and the inode is meant to interact with the
system so we have never respected the unsigned
nature of most of those fields.

not need to be signed so redefine them as
unsigned to better match the on-disk information.

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.

Change the sysinit level of tunable_mbinit() from SI_SUB_TUNABLES
to SI_SUB_KMEM after the VM is running.  This allows to use better

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.

17ebe960a6 Do not autotune ncallout to be greater than 18508.
When maxusers was unrestricted and maxfiles was allowed to autotune
much higher the result was that ncallout which was based on maxfiles
and maxproc grew much higher than was needed.

To fix this clip autotuning to the same number we would get with
the old maxusers algorithm which would stop scaling at 384
maxusers.

Growing ncalout higher is not likely to be needed since most consumers
of timeout(9) are gone and any higher value for ncallout causes the
callwheel hashes to be much larger than will even be needed for
most applications.

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

3484d5ad30 Remove the use of the ifnet send queue and if_start() in the power
save queue code.

Instead, use if_transmit() directly - and handle the cases where frame
transmission fails.

I don't necessarily like this and I think at this point the M_ENCAP check,
node freeing upon fail and the actual if_transmit() call should be done
in methods in ieee80211_freebsd.c, but I digress slightly..

This removes one of the last few uses of if_start() and the ifnet
if_snd queue.  The last major offender is ieee80211_output.c, where
ieee80211_start() implements if_start() and uses the ifnet queue
directly.

(There's a couple of gotchas here, where the if_start pointer is
compared to ieee80211_start(), but that's a later problem.)

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

eb23ab3120 Update sigcode to use both the current ABI and FreeBSD's version of the
ARM EABI syscall calling convention.

The current ABI encodes the syscall number in the instruction. This causes
issues with the thumb mode as it only has 8 bits to encode this value and
we have too many system calls and by using a register will simplify the
code to get the syscall number in the kernel.

With the ARM EABI we reuse the Linux calling convention by storing the
value in r7. Because of this we use both methods to encode the syscall
number in this function.

  Use the OFW compatible string "mips,mips4k" rather than
  "mips4k,cp0" for interrupt control using MIPS4k CP0.

  Suggested by:   thompsa

  Implement a MIPS FDT PIC decode routine to use when no PIC has been
  configured, which assumes a cascade back to the nexus bus (e.g.,
  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

In a sign of weakness, replicate the MIPS bus_space_generic.c to

  space translation for bus_space -- the solution used in NLM's MIPS
  FDT support, but possibly not quite the right thing.  This is
  inconsistent with regular I/O via the nexus and the generic
  bus_space, which instead perform translation via pmap_mapdev()
  when a resource is activated.  However, it will work while I
  attempt to identify what the right way to reconcile possible
  approaches.

  (Another approach might be to make simplebus use Nexus's activate
  routine instead of a generic one?)

This commit changes the ddt_zap_count to return error returned from
