I've been sitting on this for a year or so now; I've finally
tested it on enough devices to be reasonably sure it won't
cause too much drama. But, if you see issues, please email me.
Tested (all STA mode):
PCIe:
* AR9380
* AR9390
* AR9580
* AR9462
* AR9485
SoC:
* QCA9550
* AR9331
* AR9342
hw.x2apic_enable tunable allows disabling it from the loader prompt.
To closely repeat effects of the uncached memory ops when accessing
registers in the xAPIC mode, the x2APIC writes to MSRs are preceeded
by mfence, except for the EOI notifications. This is probably too
strict, only ICR writes to send IPI require serialization to ensure
that other CPUs see the previous actions when IPI is delivered. This
may be changed later.
In vmm justreturn IPI handler, call doreti_iret instead of doing iretd
inline, to handle corner conditions.
Note that the patch only switches LAPICs into x2APIC mode. It does not
enables FreeBSD to support > 255 CPUs, which requires parsing x2APIC
MADT entries and doing interrupts remapping, but is the required step
on the way.

If structure packed as __packed clang (and probably gcc) generates
code that loads word fields (e.g. tx_pos) byte-by-byte and if it's
modified by VideoCore in the same time as ARM loads the value result
is going to be mixed combination of bytes from previous value and
new one.

socket-buffer implementations, introduce a return value for MCLGET()
(and m_cljget() that underlies it) to allow the caller to avoid testing
M_EXT itself. Update all callers to use the return value.
With this change, very few network device drivers remain aware of
M_EXT; the primary exceptions lie in mbuf-chain pretty printers for
debugging, and in a few cases, custom mbuf and cluster allocation
implementations.
NB: This is a difficult-to-test change as it touches many drivers for
which I don't have physical devices. Instead we've gone for intensive
review, but further post-commit review would definitely be appreciated
to spot errors where changes could not easily be made mechanically,
but were largely mechanical in nature.

These variants have a few differences from the default AR9485 NIC,
namely:
* a non-default antenna switch config;
* slightly different RX gain table setup;
* an external XLNA hooked up to a GPIO pin;
* (and not yet done) RSSI threshold differences when
doing slow diversity.
To make this possible:
* Add the PCI device list from Linux ath9k, complete with vendor and
sub-vendor IDs for various things to be enabled;
* .. and until FreeBSD learns about a PCI device list like this,
write a search function inspired by the USB device enumeration code;
* add HAL_OPS_CONFIG to the HAL attach methods; the HAL can use this
to initialise its local driver parameters upon attach;
* copy these parameters over in the AR9300 HAL;
* don't default to override the antenna switch - only do it for
the chips that require it;
* I brought over ar9300_attenuation_apply() from ath9k which is cleaner
and easier to read for this particular NIC.
This is a work in progress. I'm worried that there's some post-AR9380
NIC out there which doesn't work without the antenna override set as
I currently haven't implemented bluetooth coexistence for the AR9380
and later HAL. But I'd rather have this code in the tree and fix it
up before 11.0-RELEASE happens versus having a set of newer NICs
in laptops be effectively RX deaf.

If powersave is enabled and there are any transitions to network
or full sleep - even if they're pretty damned brief - eventually
something messes up somewhere and the bus glue between the AR9331
SoC and the AR9331 wifi stops working. It shows up as stuck DMA
and LOCAL_TIMEOUT interrupts.
Both ath9k and the reference driver does a full chip reset if things
get stuck.
So:
* teach the AR9330 HAL about the force_full_reset option I added a
couple of years ago;
* if the chip is currently in full-sleep, do a full-reset;
* if TX DMA and/or RX DMA are still enabled (eg, they did get
stuck during reset) then do a full-reset.
Tested:
* AR9331 SoC, STA mode

Update the OFED Infiniband core to the version supplied in Linux
version 3.7.
The update to OFED is nearly all additional defines and functions
with the exception of the addition of additional parameters to
ib_register_device() and the reg_user_mr callback.
In addition the ibcore (Infiniband core) and ipoib (IP over Infiniband)
have both been made into completely loadable modules to facilitate
testing of the OFED stack in FreeBSD.
Finally the Mellanox Infiniband drivers are now updated to the
latest version shipping with Linux 3.7.
