Rename efx_rx_scale_support_get() to efx_rx_scale_default_support_get(),
and efx_rx_hash_support_get() to efx_rx_hash_default_support_get().
All these really report is whether an exclusive RSS context was
successfully acquired at efx_rx_init().
efx_rx_scale_support_get() sounds like it reports whether the device
supports RSS, and whether exclusive or shared contexts are supported,
but it doesn't do that. Renaming it to
efx_rx_scale_default_support_get() helps to reflect that it reports
what RSS support the client gets without trying to allocate RSS
contexts itself.
Also rename efx_rx_scale_support_t to efx_rx_scale_context_type_t, to
make the enum more suitable for specifying the type of an RSS context
to be allocated.

On Medford, with full-featured firmware running, encapsulated
packets may not be delivered unless filters are inserted for
them, as ordinary filters are not applied to encapsulated
packets. So filters for encapsulated packets need to be
inserted for each class of encapsulated packet. For simplicity,
catch-all filters are always inserted. These may match more
packets than the OS has asked for, but trying to insert more
precise filters increases complexity for little gain.

C Turt reports that the driver is not thread safe and may have
exploitable races.
Note that the proto device is intended for prototyping and development,
and is not for use on production systems. From the man page:
SECURITY CONSIDERATIONS
Because programs have direct access to the hardware, the proto
driver is inherently insecure. It is not advisable to use this
driver on a production machine.
The proto device is not included in any of FreeBSD's kernel config files
(although the module is built).
The issues in the proto device still need to be fixed, and the device is
inherently (and intentionally) insecure, but it might as well be limited
to root only.

This patch utilizes the fixed_devclass attribute in order to make sure
other acpi devices with params don't get confused for an EC device.
The existing code assumes that acpi_ec_probe is only ever called with a
dereferencable acpi param. Aside from being incorrect because other
devices of ACPI_TYPE_DEVICE may be probed here which aren't ec devices,
(and they may have set acpi private data), it is even more nefarious if
another ACPI driver uses private data which is not dereferancable. This
will result in a pointer deref during boot and therefore boot failure.
On X86, as it stands today, no other devices actually do this (acpi_cpu
checks for PROCESSOR type devices) and so there is no issue. I ran into
this because I am adding such a device which gets probed before
acpi_ec_probe and sets private data. If ARM ever has an EC, I think
they'd run into this issue as well.
There have been several iterations of this patch. Earlier
iterations had ECDT enumerated ECs not call into the probe/attach
functions of this driver. This change was Suggested by: jhb@.

This is a major update for pci_host_generic_acpi.c, the current
implementation has some gaps that are better fixed up in one go.
The changes are to:
* Follow x86 method of not adding PCI resources to PCI host bridge in
ACPI code. This has been moved to pci_host_generic_acpi.c, where we
walk thru its resources of the host bridge and add them.
* Fixup code in pci_host_generic_acpi.c to read all decoded ranges
and update the 'ranges' property. This allows us to share most of
the code with generic implementation (and the FDT one).
* Parse and setup IO ranges and bus ranges when walking the resources
above. Drop most of the changes related to this from acpica code.
* Add the ECAM memory area as mem resource 0. Implement the logic to
get the ECAM area from MCFG (using bus range which we now decode),
or from _CBA (using _BBN/bus range). Drop aarch64 ifdefs from acpica
code which did part of this.
* Switch resource activation to similar code as FDT implementation,
this can be moved into generic implementation in a later pass.
* Drop the mechanism of using the 7th bit of bus number as the domain,
this is not correct and will work only in very specific cases. Use
_SEG as PCI domain and use the bus ranges of the host bridge to
provide start bus number.
This commit should not make any functional change to dev/acpica/acpi.c
for other architectures, almost all the changes there are to revert
earlier additions in this file done for aarch64.

On arm64 (where INTRNG is enabled), the interrupts have to be mapped
with ACPI_BUS_MAP_INTR() before adding them as resources to devices.
The earlier code did the mapping before calling acpi_set_resource(),
which bypassed code that checked for PCI link interrupts.
To fix this, move the call to map interrupts into acpi_set_resource()
and that requires additional work to lookup interrupt properties.
The changes here are to:
* extend acpi_lookup_irq_handler() to lookup an irq in the ACPI
resources
* create a helper function acpi_map_intr() which uses the updated
acpi_lookup_irq_handler() to look up an irq, and then map it
with ACPI_BUS_MAP_INTR()
* use acpi_map_intr() in acpi_pcib_route_interrupt() to map
pci link interrupts.
With these changes, we can drop the ifdefs in acpi_resource.c, and
we can also drop the call for mapping interrupts in generic_timer.c

The current quirk implementation writes a fixed address to the PCI BAR

change depending on PCI devices present. So using a fixed address here
is not correct.
This quirk worked around a firmware bug that programmed the MSI-X bar
of the SATA controller incorrectly. The newer firmware does not have
this issue, so it is better to drop this quirk altogether.
