- Move intr_disable() and intr_restore() from acpi_wakeup.c to acpi.c
and call AcpiLeaveSleepStatePrep() in interrupt disabled context.
- Add acpi_wakeup_machdep() to execute wakeup MD procedures and call
it twice in interrupt disabled/enabled context (ia64 version is
just dummy).
- Rename wakeup_cpus variable in acpi_sleep_machdep() to suspcpus in
order to be shared by acpi_sleep_machdep() and acpi_wakeup_machdep().
- Move identity mapping related code to acpi_install_wakeup_handler()
(i386 version) for preparation of x86/acpica/acpi_wakeup.c
(MFC candidate).

DEVICE_RESUME() should be done before AcpiLeaveSleepState() because
PCI config space evaluation can be occurred during control method
executions.
This should fix one of the hang up problems on resuming.

These aren't strictly needed at the moment as we're not doing APSM
and forcing the NIC in and out of network sleep. But, they don't hurt.
Tested:
* AR9280 (mini-PCIe)
Obtained from: Qualcomm Atheros, Linux ath9k
* Now that ah_configPCIE is called for both power on and suspend/resume,
make sure the right bit(s) are cleared and set when suspending and
resuming. Specifically:
+ force disable/enable the PCIe PHY upon suspend/resume;
+ reprogram the PCIe WAR register when resuming and upon power-on.
* Add a recipe which powers down any PCIe PHY hardware inside the AR5416
(which is the PCI variant) to save on power. I have (currently) no way
to test exactly how much power is saved, if any.
Tested on:
* AR5416 cardbus - although unfortunately pccard/cbb/cardbus currently
detaches the NIC upon suspend, I don't think it's a proper test case.
* AR5418 PCIe attached to expresscard - since we're not doing PCIe APSM,
it's also not likely a full/good test case.
In both instances I went through a handful of suspend/resume cycles and
ensured that the STA vap reassociated correctly.
TODO:
* Setup a laptop to simply sit in a suspend/resume loop, making sure that
the NIC always correctly comes back;
* Start doing suspend/resume tests with actual traffic going on in the
background, as I bet this process is all quite racy at the present;
* Test adhoc/hostap mode, just to be completely sure it's working correctly;
* See if I can jury rig an external power source to an AR5416 to test out
whether ah_disablePCIE() works.
Obtained from: Qualcomm Atheros
* Add some other WAR bits (very usefully described too) in preparation for
porting over some suspend/resume fixes from ath9k/Atheros.

Extend the enablepci method to have a "poweroff" flag, which if equal
to true means the hardware is about to go to sleep.

* Flesh out the pcie disable method for 11n chips, as they were defaulting
to the AR5212 (empty) PCIe disable method.
* Add accessor macros for the HAL PCIe enable/disable calls.
* Call disable on ath_suspend()
* Call enable on ath_resume()
NOTE:
* This has nothing to do with the NIC sleep/run state - the NIC still
will stay in network-run state rather than supporting network-sleep
state. This is preparation work for supporting correct suspend/resume
WARs for the 11n PCIe NICs.
TODO:
* It may be feasible at this point to keep the chip powered down during
initial probe/attach and only power it up upon the first configure/reset
pass. This however would require correct (for values of "correct")
tracking of the NIC power configuration state from the driver and that
just isn't attempted at the moment.
Tested:
* AR9280 on my Lenovo T60, but with no suspend/resume pass (yet).
Significantly update tcp_lro for mostly two things:
1) introduce basic support for IPv6 without extension headers.
2) try hard to also get the incremental checksum updates right,
especially also in the IPv4 case for the IP and TCP header.
Move variables around for better locality, factor things out into
functions, allow checksum updates to be compiled out, ...
Leave a few comments on further things to look at in the future,
though that is not the full list.
Update drivers with appropriate #includes as needed for IPv6 data
type in LRO.
