93929f253d sfxge: Separate software Tx queue limit for non-TCP traffic
Add separate software Tx queue limit for non-TCP traffic to make total
limit higher and avoid local drops of TCP packets because of no
backpressure.
There is no point to make non-TCP limit high since without backpressure
UDP stream easily overflows any sensible limit.

Split early drops statistics since it is better to have separate counter
for each drop reason to make it unabmiguous.

Add software Tx queue high watermark. The information is very useful to
understand how big queues grow under traffic load.

76c8553679 sfxge: Remove extra cache-line alignment and reorder sfxge_evq_t
Remove the first member alignment to cacheline since it is nop.
Use __aligned() for the whole structure to make sure that the structure
size is cacheline aligned.
Remove lock alignment to make the structure smaller and fit all members
used on event queue processing into one cacheline (128 bytes) on x86-64.
The lock is obtained as well from different context when event queue
statistics are retrived from sysctl context, but it is infrequent.
Reorder members to avoid padding and go in usage order on event
processing.
As the result all structure members used on event queue processing fit
into exactly one cacheline (128 byte) now.

In fact the pointer is used only if more than one TXQ is processed in

It is used (read-write) on completion path only.
Also it makes the first part of the structure smaller and it fits now

85f95fffd7 hook userland threads suspend + resume into acpi suspend code
Also, split power_suspend into power_suspend and power_suspend_early.

power_suspend_early is called before the userland is frozen.
power_suspend is called after the userland is frozen.

Currently only VT switching is hooked to power_suspend_early.
This is needed because switching away from X server requires its
cooperation, so obviously X server must not be frozen when that happens.

Freezing userland during ACPI suspend is useful because not all drivers
correctly handle suspension concurrent with other activity.  This is
especially applicable to drivers ported from other operating systems
that suspend all software activity between placing drivers and hardware
into suspended state.
In particular drm2/radeon (radeonkms) depends on the described
procedure.  The driver does not have any internal synchronization
between suspension activities and processing of userland requests.

Many thanks to kib for the code that allows to freeze and thaw all
userland threads.

Note that ideally we also need to park / inhibit (non-special) kernel
threads as well to ensure that they do not call into drivers.

6dfa4578d6 vt(4): Use power_{suspend,resume} event handlers to implement
suspend/resume

The goal is to avoid that the vt(4) resume happens before the video
display is resumed. The original patch was provided by Andriy Gapon.

This new patch registers the handlers in vt_upgrade(). This is done
once, thanks to the VDF_ASYNC flag. I abused this flag because it was
already abused by the keyboard allocation. The event handlers then call
the backend if it provides callbacks for suspend/resume.

6b0e9233e4 Rework vtblk dump handling of in flight requests
Previously, the driver resets the device and abandon the requests that
are caught in flight when the dump was initiated. This was problematic
if the system is resumed after the dump is completed.

While that is probably not the typical action, it is simple to rework
the driver to very likely have the device usable after the dump without
making it more likely for the dump to fail. The in flight requests are
simply queued for completion once the dump is finished.

35d002dc8f Fix SCSI status byte reporting on 4Gb and 8Gb Qlogic boards.
The newer boards don't have the response field that indicates
whether the SCSI status byte is present.  You have to just look to
see whether it is non-zero.

The code was looking to see whether the sense length was valid
before propagating the SCSI status byte (and sense information) up
the stack.  With a status like Reservation Conflict, there is no
sense information, only the SCSI status byte.  So it wasn't getting
correctly returned.

isp.c:
	In isp_intr(), if we are on a 2400 or 2500 type board and
	get a response, look at the actual contents of the
	SCSI status value and set the RQSF_GOT_STATUS flag

	actual sense information returned.

4098ccafa4 Revise the arm bus_space implementation to avoid dereferencing the tag on
every operation to retrieve the bs_cookie value almost nothing actually uses.

The bus_space struct contains a private data pointer (poorly named bs_cookie,
now renamed to bs_privdata) which is used only by a few old armv4 xscale
implementations.  The bus_space functions were all defined to take this
value as the first parameter instead of the bus_space_tag_t, requiring all
the inline macro and function expansions to dereference the tag to pass it
to another function, which never uses it.  Now all the functions take the tag
as the first parameter and retrieve the privdata if they need it.

Also fix a couple bus_space_unmap() implementations that were calling
kva_free() instead of pmap_unmapdev().

b2bdc62a95 Refactor / restructure the RSS code into generic, IPv4 and IPv6 specific
bits.

The motivation here is to eventually teach netisr and potentially
other networking subsystems a bit more about how RSS work queues / buckets
are configured so things have a hope of auto-configuring in the future.

* net/rss_config.[ch] takes care of the generic bits for doing
  configuration, hash function selection, etc;
* topelitz.[ch] is now in net/ rather than netinet/;
* (and would be in libkern if it didn't directly include RSS_KEYSIZE;
  that's a later thing to fix up.)
* netinet/in_rss.[ch] now just contains the IPv4 specific methods;
* and netinet/in6_rss.[ch] now just contains the IPv6 specific methods.

This should have no functional impact on anyone currently using
the RSS support.

with the bus running at frequencies between 25-50MHz (which shouldn't work).

This is the solution adopted by U-Boot and other OSes (linux and *BSD)
for the timeouts on Raspberry Pi boards with certain SD cards.  Some
research shows that this quirk is also used on a few other boards, so the
fix is a generic quirk instead of being in the RPi-specific driver code.

This change is based on information discovered by Michal Meloun.

e21928d3c3 Until there's a full MCI implementation - just implement a placeholder
MCI bluetooth coexistence method for WB222.

The rest of MCI requires a bunch more work, including adding a DMA buffer
for the MCI hardware to bounce messages in/out of and handling MCI
interrupts.  But the more important part here is telling the HAL
the btcoex is enabled and MCI is in use so it configures the correct
initial bluetooth parameters in the wireless NIC and configures
things like bluetooth traffic weights and such.

So, this at least gets the HAL to do some of the right things in
configuring the inital bluetooth coexistence stuff, but doesn't
actually do full btcoex.  That'll take.. some effort.

Tested:

* AR9462 (WB222), STA mode

8b91d5b008 Various interrelated fixes to make suspend / resume work better. We now
can suspend / resume and unload / load cbb and cardbus without errors
on my Lenovo T400, which wasn't possible before. Cards suspending
and resuming in the CardBus slot not yet tested.
o Enable memory cycles to the bridge early (as part of the new
  cbb_pci_bridge_init). This fixes the Bad VCC errors which were
  caused by the code accessing the device registers with this
  cleared. The suspend / resume process clears it.
o Refactor suspend / resume into bus specific code (though the ISA
  code is just stubbed). This isn't strictly necessary, but makes
  the initializaiton code more uniform and should be more bullet
  proof in the face of variant behavior among cardbus bridges.
o Fixup comments in the power-up sequence to reflect reality. These
  comments were written for one regime of power-up, but not updated
  as things were revised.
o Add a paranoid small delay (100ms) to cover noisy cards powering
  down.
o Fix some debugging prints to be easier to grep from dmesg.

b78e84d132 Resolve a special case deadlock: When two or more threads are
simultaneously detaching kernel drivers on the same USB device we can
get stuck in the "usb_wait_pending_ref_locked()" function because the
conditions needed for allowing detach are not met. The "destroy_dev()"
function waits for all system calls involving the given character
device to return. Character device system calls may lock the USB
enumeration lock, which is also held when "destroy_dev()" is
called. This can sometimes lead to a deadlock not noticed by
WITNESS. The current solution is to ensure the calling thread is the
only one holding the USB enumeration lock and prevent other threads
from getting refs while a USB device detach is ongoing. This turned
out not to be sufficient. To solve this deadlock we could use
"destroy_dev_sched()" to schedule the device destruction in the
background, but then we don't know when it is safe to free() the
private data of the character device. Instead a callback function is
executed by the USB explore process to kill off any leftover USB
character devices synchronously after the USB device explore code is
finished and the USB enumeration lock is no longer locked. This makes
porting easier and also ensures us that character devices must
eventually go away after a USB device detach.

While at it ensure that "flag_iserror" is only written when "priv_mtx"
is locked, which is protecting it.
