a boot-bus controller the i2c are said to not be a PCF8584). Similar to the
SUNW,envctrl devices, onboard slaves for monitoring fans, temperatures and
such hang off of these i2c devices. But there's also stuff like EEPROMs
housing the hostid of the system and the boards usally have a connector to
add custom slave devices (on CP1500 there's actually a second PCF8584 with
its own I2C bus for these).
This driver already works fine but I'm not yet sure if access to the slave
devices on CP1400/CP1500 marked as "reserved for factory use" in the docs
should be blocked (most likely these are the voltage controllers wich aren't
meant to be controller by software and even not by the firmware). Once the
issues with polled mode are fixed in the common pcf(4) part in pcf.c, this
front-end should probably honour the poll-mode property of the i2c devices.

- In subr_ndis.c, my_strcasecmp() actually behaved like my_strncasecmp():
we really need it to behave like the former, not the latter. (It was
falsely matching "RadioEnable", which defaults to 1 with "RadioEnableHW"
which the driver creates itself and to 0, because we were using
strlen("RadioEnable") as the length to test. This caused the radio to
always be turned off. :( )
- In if_ndis.c, only set IEEE80211_CHAN_A for channels if we actually
set any IEEE80211_MODE_11A rates. (ieee80211_attach() will "helpfully"
add IEEE80211_MODE_11A to ic_modecaps for you if you initialize any
802.11a channels. This caused "ndis0: 11a rates:" to erroneously be
displayed during driver load.)
- Also in if_ndis.c, when using TESTSETRATE() to add in any missing 802.11b
rates, remember to OR the rates with IEEE80211_RATE_BASIC, otherwise
comparing against existing basic rates won't match. (1, 2, 5.5 and
11Mbps are basic rates, according to the 802.11b spec.) This erroneously
cause 11Mbps to be added to the 11b rate list twice.

This is part 2/2 of fixing autonegotiation on hme(4) using DP83840A PHYs.

properly. This causes the autonegotiation to e.g. never establish a
100baseTX full-duplex link. The solution to this problem is to manually
write the capabilities from the BMSR to the ANAR every time a media
change occurs, even when already in autonegotiation mode.
The NetBSD way of doing this is to set their MIIF_FORCEANEG flag in the
NIC driver. This causes mii_phy_setmedia() to call mii_phy_auto() (which
will set the ANAR according to the BMSR) even when the PHY alread is in
autonegotiation mode. However, while doing the same on FreeBSD (which
involves porting the MIIF_FORCEANEG flag and converting nsphy.c to use
mii_phy_setmedia()) fixes autonegotiation, using mii_phy_setmedia()
causes this driver to no longer work properly in the other modes.
Another drawback of that approach is that this will also force writing
the ANAR on other PHYs whose drivers use mii_phy_setmedia() and which
are used with a NIC whose driver sets MIIF_FORCEANEG (e.g. hme(4) is
known to be used together with 3 different PHYs while only the DP83840A
require this workaround).
So instead of moving to MIIF_FORCEANEG, just call mii_phy_auto() in
nsphy_service() unconditionally when hanging off of a hme(4) and serving
a media change

make the key name matching case-insensitive. There are some drivers
and .inf files that have mismatched cases, e.g. the driver will look
for "AdhocBand" whereas the .inf file specifies a registry key to be
created called "AdHocBand." The mismatch is probably a typo that went
undetected (so much for QA), but since Windows seems to be case-insensitive,
we should be too.
In if_ndis.c, initialize rates and channels correctly so that specify
frequences correctly when trying to set channels in the 5Ghz band, and
so that 802.11b rates show up for some a/b/g cards (which otherwise
appear to have no 802.11b modes).
Also, when setting OID_802_11_CONFIGURATION in ndis_80211_setstate(),
provide default values for the beacon interval, ATIM window and dwelltime.
The Atheros "Aries" driver will crash if you try to select ad-hoc mode
and leave the beacon interval set to 0: it blindly uses this value and
does a division by 0 in the interrupt handler, causing an integer
divide trap.

does not reliably prevent the triggering of interrupts for all supported
configurations. Thus, the FIFO size probe could cause an interrupt,
which could lead to an interrupt storm in the shared interrupt case.
To prevent this, change ns8250_bus_probe() to use the overflow bit in
the line status register instead of the RX ready bit in the interrupt
identification register to detect whether the FIFO has filled up.
This allows us to clear all bits in the interrupt enable register during
the probe, which should prevent interrupts reliably.
Additionally, the detected FIFO size may be a bit more accurate, because
the overflow bit is only set when the FIFO did actually fill up, while
interrupts would trigger a bit early.

This splits the driver into a bus-independant backend, plus bus-specific

frontend in envctrl.c is for sparc64/Ebus2 (Sun device name: SUNW,envctrl

This is not yet ready for public consumption, but it basically works.

in the various pci specifications as readonly. vendor, subvendor,
device and subdevice are required to be loaded in hardware by some
means that isn't the system BIOS or other system software (although
some devices do have ways of accomplishing this). class and subclass
are defined to be read-only in section 6.2.1 (v2.2). Apart from the
status register, which we weren't touching, these are the only
read-only registers I could find in the 2.2 spec.
progif is also defined as being read-only in section 6.2.1. However,
the PCI IDE programming document specifically states that some of the
bits are read/write. Since we may have to restore registers before we
have a driver attached, go ahead and restore this one byte when
transitioning between D3 and D0.
The PCI spec also says that writes to reserved and unimplemented
registers must be completed normally. It makes no statements about
writes to read-only registers, so be as conservative as possible,
while covering the exception to the rule that is documented in a
subpart of the standard.
