happen on the first management frame received from a neighbor; we assume
any merge candidate will send more frames and those should be processed
with a suitable table entry.

interrupts that have a trigger mode of conforming. This fixes problems on
some older machines that still route PCI devices via ISA interrupts when
using an I/O APIC.

instead of burying that in the atpic(4) code as atpic(4) is not the only
user of elcr(4). Change the elcr(4) code to export a global elcr_found
variable that other code can check to see if a valid ELCR was found.

producers rather than consumers as new-bus resources only handle consumed
resources. We already do this for the other ACPI resource types that
support the producer/consumer attribute.
Hold a lock on the table instead of futzing with reference counts which
was potentially dangerous except drivers were quiescent while we did this
so the table contents never changed. Disable the hack logic for removing
scan candidates with multiple association failures; it's never done the
right thing and will be fixed correctly with background scanning goes in.
object (/) rather than the pci bus object when walking the _PRT to force
attach devices. We already look up relative to the root object when doing
interrupt routing.

For such devices, we require _PRS to exist and we warn if any of the
resources in _PRS are not IRQ resources (since we'll have no way of knowing
which of those resources to use without a working _CRS). When it does
come time to set resources, we build up a resource buffer from scratch
as we do for devices with _CRS that only have IRQ resources.
- Fix a bug with setting extended IRQ resources where we set the IRQ value
in the wrong resource structure meaning that whichever IRQ was listed in
_PRS was used instead. This might fix some weird issues on certain boxes
where IRQs > 16 don't seem to work when using ACPI.
- Fix a bug with how we walked the resource buffer after _SRS to call
config_intr() in that the 'end' variable was not properly updated, so we
could either terminate the loop early or loop after the end of the
buffer.

not we're going to process the frame; this makes the counters reflect frames
actually processes instead of received (discarded frames were already counted)
o increase the max per-frame tx descriptor count and the number of tx
buffers for forthcoming fast frame support
o correct the max scatter/gather count; it cannot be larger than the
max(tx,rx,beacon) descriptor counts
instead use the FPU to convert subnormals to normals. (NB: Further
simplification is possible, such as using the FPU for the rounding
step.)
This fixes a bug reported by stefanf where long double subnormals in
the Intel 80-bit format would be output with one fewer digit than
necessary when the default precision was used.
(fix imported from madwifi by Takanori Watanabe)
o eliminate save/restore of pci registers handled by the system
o eliminate duplicate zero of the softc (noted by njl)
o consolidate common code

and always has been, but the system call itself returns
errno in a register so the problem is really a function of
libc, not the system call.
