We don't have a separate bss node; instead we dup the first node we saw
and turn that into the BSS node. This means that action frames from
that node would be rejected.
So, check that the node is the bss node /and/ the MAC doesn't match ni_macaddr.
That's the "right" way for now to verify it's an unknown node.
This fixes handling action frames in adhoc mode, which includes negotiating
11n aggregation via ADDBA/DELBA.
This by itself isn't enough to correctly create 11n adhoc networks; but
it is required for aggregation to be negotiated.
Tested:
* AR9380, 11n adhoc mode
* broadcom 11ac adhoc (vendor platform)

- Add missing va_end's after corresponding va_start's to cleanup state
- Eliminate questionable bzero'ing of va_list passed in to
do_buff_decode(..) and do_encode(..) from buff_{de,en}code_visit(..)
and csio_{de,en}code_visit(..). Make va_list a pointer instead and
pass NULL into the underlying functions to handler this in a portable
way.
- Do some minor style(9) clean up in affected functions.

a resource is activated. Also, mention the wrapper API that accepts a
struct resource instead of a bus tag and handle.
Instead of copy-pasting the string literal for "UTC" 3 times and using

On ARM, we can directly switch between translation tables only when
the size of the mapping for any given virtual address is the same in
the old and new translation tables. The load of new TTB and subsequent
TLB flush is not atomic operation. So speculative page table walk can
load TLB entry from new mapping while rest of TLB entries are still the
old ones. In worst case, this can lead to situation when TLB cache can
contain multiple matching TLB entries. One (from old mapping) L2 entry
for VA + 4k and one (from new mapping) L1 entry for VA.
Thus, we must switch to kernel pmap translation table as intermediate
mapping because all sizes of these (old pmap and kernel pmap) mappings
are same (or unmapped). The same is true for switch from kernel pmap
translation table to new pmap one.
Add new function gpio_alloc_intr_resource(), which allows an allocation
of interrupt resource associated to given gpio pin. It also allows to
specify interrupt configuration.
Note: This functionality is dependent on INTRNG, and must be
implemented in each GPIO controller.
Summary:
The Initial Local APIC ID is returned by CPUID function 1 (in EBX).
On AMD Family 10h systems the way that ID is built is controlled by
an MSR bit (InitApicIdCpuIdLo). BKDG instructs BIOS to set it in a
certain way, but a BIOS can be buggy. In that case the ID can confuse
tools that use it, e.g. hwloc.
For example, on a system that I own real Local APIC IDs are configured
as 0, 1, 2, 3, but IDs reported via CPUID.1 are 0, 0x40, 0x80, 0xc0.

In principle n is only used to carry a copy of ipi_count, which is
unsigned, in the non-VIMAGE case, however ipi_count can be used
directly so it is not needed at all. Removing it makes things look
cleaner.
The "len" parameter is uint32_t, indexing it with an int may
end up in a signed integer overflow.
strlen(3) returns an integer of size_t so the corresponding index should
have that size.

This allows the PCI-PCI bridge driver to save a reference to the child
device in its softc.
Note that this required moving the "pci" device creation out of
acpi_pcib_attach(). Instead, acpi_pcib_attach() is renamed to
acpi_pcib_fetch_prt() as it's sole action now is to fetch the PCI
interrupt routing table.

'devctl delete' can be used to delete a device that is no longer present.
As an anti-foot-shooting measure, 'delete' will not delete a device
unless it's parent bus says it is no longer present. This can be
overridden by passing the force ('-f') flag.
Note that this command should be used with care. If a device is deleted
that is actually present it can't be resurrected unless the parent bus
device's driver supports rescans.

Rescanning a PCI bus uses the following steps:
- Fetch the current set of child devices and save it in the 'devlist'
array.
- Allocate a parallel array 'unchanged' initalized with NULL pointers.
- Scan the bus checking each slot (and each function on slots with a
multifunction device).
- If a valid function is found, look for a matching device in the 'devlist'
array. If a device is found, save the pointer in the 'unchanged' array.
If a device is not found, add a new device.
- After the scan has finished, walk the 'devlist' array deleting any
devices that do not have a matching pointer in the 'unchanged' array.
- Finally, fetch an updated set of child devices and explicitly attach any
devices that are not present in the 'unchanged' array.
This builds on the previous changes to move subclass data management into
pci_alloc_devinfo(), pci_child_added(), and bus_child_deleted().
Subclasses of the PCI bus use custom rescan logic explicitly override the
rescan method to disable rescans.
