method is used by the PCI bus driver to query the power management system
to determine the proper device state to be used for a device during suspend
and resume. For the ACPI PCI bridge drivers this calls
acpi_device_pwr_for_sleep(). This removes ACPI-specific knowledge from
the PCI and PCI-PCI bridge drivers.

If it does, don't then try reprogramming the NF "cap" values (ie
what values are the "maximum" value the NF can be) - instead,
just leave the current CCA value as the NF cap.
This was inspired by some similar work from ath9k. It isn't
a 100% complete solution (as there may be some reason where a
high NF CCA/cap is written, causing the baseband to stop thinking it
is able to transmit, leading to stuck beacon and interface reset)
which I'll investigate and look at fixing in a later commit.

This is not necessarily the case for AR5416 and later chipsets.

flag immediately so it's only set once per longcal interval.
Without this, the current AR5416 code will continuously spam NF
calibrations during a periodic calibration if the longcal flag
is set. The longcal flag wouldn't be cleared until the calibration
method indicates that calibrations are "complete".
This drops the rate of NF calibration updates down from "once every
shortcal" (ie, every 100ms) during a periodic calibration, to only
once per "longcal" interval. Spamming NF calibrations every 100ms
caused some potentially horrific issues in noisy environments as
NF calibrations can take longer than 100ms and this spamming can
cause invalid NF calibration results to be read back - leading to
missed beacons, and thus leading to a stuck beacon situation.
Stuck beacons cause interface resets, which restart calibrations.
This means that the longcal calibration runs every 100ms (shortcal)
until all initial calibrations are completed. This spamming can then
cause the above issues which leads to stuck beacons, leading to
interface resets, etc, etc. Quite annoying.
within the device table. This code uses the same algorithm as used in the
Linux, NetBSD and DragonflyBSD driver.
While investigating this, it became apparent that the Linux driver always
initialises the device, and not just in the PL2303HX case. Change
uplcom(4) to do the same.
This change allows us to synchronize our device ID list with Linux and
NetBSD, without requiring knowledge of the chipset in use.

L2CB/B2(AR8152). This change adds supports for the following
controllers.
o AR8151 v1.0(L1D) gigabit ethernet controller
o AR8151 v2.0(L1D) gigabit ethernet controller
o AR8152 v1.1(L2CB) fast ethernet controller
o AR8152 v2.0(L2CB2) fast ethernet controller
These controllers have the same feature of AR8131/AR8132 and

- Increase target limit from 4 to 64; this limit will be removed entirely
at a later time.
- Improve recovery from lost network connections.
- Fix some potential deadlocks and a serious memory leak.
- Fix incorrect use of MH_ALIGN (instead of M_ALIGN), which makes no
practical difference, but triggers a KASSERT with INVARIANTS.
- Fix some warnings in iscontrol(8) and improve the man page somewhat.

like memory mapped register access. Typical problem from the issue
was MII access returned unreliable values. I'm not sure this comes
from lack of register flushing in MII access after accessing
STE_PHYCTL register though.
To address the issue, read hints data that controls which type of
memory mapping should be used in driver. ste(4) still prefers
memory mapping to io mapping but honor hints entered by user except
for controllers that have problems with memory mapping.
The hint to use iomapping could be given by adding the following
line to /boot/device.hints file.
