Make ix_crcstrip a public symbol for the moment; it probably is not
the right solution but I will leave it to experts to untangle this
problem to properly stop the build failures.
At the moment only if_ix.c includes dev/netmap/ixgbe_netmap.h which is
good as ixgbe_netmap.h defines a couple of (file) static variables--thus
local to if_ix.c.
static int ix_crcstrip however now also got checked from ix_txrx.c

Add GPIO function mux configuration for AR934x SoCs.
The AR934x (and maybe others in this family) have a more complicated
GPIO mux. The AR71xx just has a single function register for a handful
of "GPIO or X" options, however the AR934x allows for one of roughly
100 behaviours for each GPIO pin.
So, this adds a quick hints based mechanism to configure the output
functions, which is required for some of the more interesting board
configurations. Specifically, some use external LNAs to improve
RX, and without the MUX/output configured right, the 2GHz RX side
will be plain terrible.
It doesn't yet configure the "input" side yet; I'll add that if
it's required.
Tested:
* TP-Link TL-WDR3600, testing 2GHz STA/AP modes, checking some
basic RX sensitivity things (ie, "can I see the AP on the other
side of the apartment that intentionally has poor signal reception
from where I am right now.")
Whilst here, fix a silly bug in the maxpin routine; I was missing
a break.

Disable timestamping on devfs read/write operations by default.
Currently we update timestamps unconditionally when doing read or
write operations. This may slow things down on hardware where
reading timestamps is expensive (e.g. HPET, because of the default
vfs.timestamp_precision setting is nanosecond now) with limited
benefit.
A new sysctl variable, vfs.devfs.dotimes is added, which can be
set to non-zero value when the old behavior is desirable.

Allow to override default kernel virtual address assignment on ARM
Each plaform performs virtual memory split between kernel and user space
and assigns kernel certain amount of memory space. However, is is sometimes
reasonable to change the default values. Such situation may happen on
systems where the demand for kernel buffers is high, many devices occupying
memory etc. This of course comes with the cost of decreasing user space
memory range so shall be used with care. Most embedded systems will not
suffer from this limtation but rather take advantage of this potential
since default behavior is left unchanged.

Use VT-d interrupt remapping block (IR) to perform FSB messages
translation. In particular, despite IO-APICs only take 8bit apic id,
IR translation structures accept 32bit APIC Id, which allows x2APIC
mode to function properly. Extend msi_cpu of struct msi_intrsrc and
io_cpu of ioapic_intsrc to full int from one byte.
KPI of IR is isolated into the x86/iommu/iommu_intrmap.h, to avoid
bringing all dmar headers into interrupt code. The non-PCI(e) devices
which generate message interrupts on FSB require special handling. The
HPET FSB interrupts are remapped, while DMAR interrupts are not.
For each msi and ioapic interrupt source, the iommu cookie is added,
which is in fact index of the IRE (interrupt remap entry) in the IR
table. Cookie is made at the source allocation time, and then used at
the map time to fill both IRE and device registers. The MSI
address/data registers and IO-APIC redirection registers are
programmed with the special values which are recognized by IR and used
to restore the IRE index, to find proper delivery mode and target.
Map all MSI interrupts in the block when msi_map() is called.
Since an interrupt source setup and dismantle code are done in the
non-sleepable context, flushing interrupt entries cache in the IR
hardware, which is done async and ideally waits for the interrupt,
requires busy-wait for queue to drain. The dmar_qi_wait_for_seq() is
modified to take a boolean argument requesting busy-wait for the
written sequence number instead of waiting for interrupt.
Some interrupts are configured before IR is initialized, e.g. ACPI
SCI. Add intr_reprogram() function to reprogram all already
configured interrupts, and call it immediately before an IR unit is
enabled. There is still a small window after the IO-APIC redirection
entry is reprogrammed with cookie but before the unit is enabled, but
to fix this properly, IR must be started much earlier.
Add workarounds for 5500 and X58 northbridges, some revisions of which
have severe flaws in handling IR. Use the same identification methods
as employed by Linux.
