* arge0 doesn't (yet) work via the switch PHY ports; I'm not sure why.
* arge1 maps to the WAN port. That works.
TODO:
* The PLL register needs a different (non-default) value for Gigabit
Ethernet. The board setup code needs to be extended a bit to allow
for non-default pll_1000 values - right now, those values come out
of hard-coded values in the per-chip set_pll_ge() routines.

This may result in a bit of a throughput drop. However, any throughput
drop at this point should be investigated and root caused, as it's likely
because TX scheduling (all the way down to how preemption, scheduler work,
etc) is happening in a sub-optimal fashion.
This also makes it much more likely to be reloadable on a live machine.
Allocating 5120 TX ath_buf entries via contigmalloc is very unlikely
after a few hours of using X/Chromium.
it respects PACKAGESITE, PACKAGEROOT, and a new environment variable ABI (if a user want to use a different API from the base one for its packages)
it has no man page on purpose to avoid hidding the pkg(8) man page from the pkgng package.
for now uses pkgbeta.FreeBSD.org as default mirror to find its package
it respects MK_PKGTOOLS

dirty and murky past.
* Override the default cache line size to be something reasonable if
it's set to 0. Some NICs initialise with '0' (eg embedded ones)
and there are comments in the driver stating that various OSes (eg
older Linux ones) would incorrectly program things and 0 out this
register.
* Just default to overriding the latency timer. Every other driver
does this.
* Use a default cache line size of 32 bytes. It should be "reasonable
enough".

virtio_balloon: Do the notify outside of the lock
By the time we return from virtqueue_notify(), the descriptor

virtqueue: Add support for VIRTIO_F_RING_EVENT_IDX
This can be used to reduce the number of guest/host and
host/guest interrupts by delaying the interrupt until a
certain index value is reached.
Actual use by the network driver will come along later.

virtqueue: Simplify virtqueue_nused()
Since the values just wrap naturally at UINT16_MAX, we
can just subtract the two values directly, rather than
doing 2's complement math.

virtio_blk: Remove debugging crud from 75dd732a
There seems to be an issue with Qemu (or FreeBSD VirtIO) that sets
the PCI register space for the device config to bogus values. This
only seems to happen after unloading and reloading the module.

r233961:
Fix interrupt load balancing regression, introduced in revision
222813, that left all un-pinned interrupts assigned to CPU 0.
In intr_shuffle_irqs(), remove CPU_SETOF() call that initialized
the "intr_cpus" cpuset to only contain CPU0.
This initialization is too late and nullifies the results of calls
to the intr_add_cpu() that occur much earlier in the boot process.
r234074 (partial):
The BSP is not added to the mask of valid target CPUs for interrupts.
Fix this by adding the BSP as an interrupt target directly in
r234105:
Fix !SMP build after r234074.

int (*compar)(const struct dirent **, const struct dirent **)
The current code defines sortq() to accept two void *, then cast them
to const struct dirent **. Because the code does not really need this
cast, we can eliminate the casts by changing the function prototype
to match scandir(3) expectation.
MFC after: 1 month
Contrarily to what i wrote in my previous commit, the 82599
does include the CRC in the length. The operating mode is
reset in ixgbe_init_locked() and so we need to hook into
the places where the two registers (HLREG0 and RDRXCTL) are
modified.
