Previously we had to do it synchronously because we could not drop the lock
due to potential scratch memory use conflicts. Previous commits fixed that
collision, so here it goes -- slower and less reliable external requests
are executed asynchronously without spinning in tight loop and with more
safe timeout handling.
This fixes a conflict with the M_B macro in powerpc's
<machine/db_machdep.h> exposed by the recent addition of DDB commands
to the cxgbe driver.

Usually IOCBs should be put on queue for asynchronous processing and should
not require additional DMA memory. But there are some cases like aborts and
resets that for external reasons has to be synchronous. Give those cases
separate 2*64 byte DMA area to decouple them from other DMA scratch area
users, using it for asynchronous requests.
While the same update is also available for 24xx chips, it seems have
a problem with disabling virtual ports -- firmware handles the request,
but does not respong on it, causing timeout in driver.

"how" argument is passed as value of int* pointer to callback
function but dereferenced as char* so only one byte taken into
into account. On little-endian systems it happens to work because
first byte is LSB that contains actual value, on big-endian it's
MSB and in this case it's always equal zero

VM_NUMA_ALLOC is used to enable use of domain-aware memory allocation in
the virtual memory system. DEVICE_NUMA is used to enable affinity
reporting for devices such as bus_get_domain().
MAXMEMDOM must still be set to a value greater than for any NUMA support
to be effective. Note that 'cpuset -gd' always works if MAXMEMDOM is
enabled and the system supports NUMA.

don't do the syncbeacon call if we miss beacons outside of STA mode.
* Don't do the IBSS merge bits if the current node plainly won't ever

Previously, the ACPI PCI bus driver did a single pass over the devices in
the namespace that were a child of a given PCI bus to associate the
PCI bus-enumerated device_t devices with the corresponding ACPI handles.
However, this meant that handles were only established at runtime for devices
found during the initial PCI bus scan.
PCI_IOV adds devices that show up after the initial PCI bus scan, and coming
changes to add a bus rescan can also add devices after the initial scan.
This change adds a pci_child_added() callback to the ACPI PCI bus that walks
the namespace to find the ACPI handle for each device that is added. Using
a callback means that the handle is correctly set for any device no matter
how it is added (initial scan, IOV, or a bus rescan).
The SoCs I've tried the driver with include the following:
RT3050, RT5350, RT3662, RT3883, MT7620, MT7621, MT7688.
On boards, based on the above SoCs traffic is passing through correctly
and the boards survive a flood ping with very little or no drops (drops
may be caused elsewhere in my test setup, however).
One issue still remains and needs to be fixed in the future: if_rt does
not survive an ifconfig rt0 down/ifconfig rt0 up cycle.
This issue existed before this commit as well, however.
