o add IEEE80211_F_JOIN flag to ieee80211_fix_rate to indicate a station
is joining a BSS; this is used to control whether or not we over-write
the basic rate bit in the calculated rate set
o fix ieee80211_fix_rate to honor IEEE80211_F_DODEL when IEEE80211_F_DONEGO
is not specified (e.g. when joining an ibss network)
o on sta join always delete unusable rates from the negotiated rate set,
this was being done only ibss networks but is also needed for 11g bss
with mixed stations
o on sta join delete unusable rates from the bss node's rate set, not the
scan table entry's rate set
o when calculating a rate set for new neighbors in an ibss caculate a
negotiated rate set so drivers are not presented with rates they should
not use

- Clear the PCI AFSR and status error bits as previous errors still
might be indicated.
- Set up the PCI control and diagnostic registers according to the
capabilities, workarounds, etc of/for specific revisions of the
supported bridges. This includes no longer setting Hummingbird-/
Sabre-specific bits in the PCI control register but preserving
what the firmware has initialized them to like OpenSolaris does.
Previously we were setting these bits according to the example in
the Sabre documentation, which I doubt is appropriate for all
Sabre based designs and especially not for Hummingbirds. This
also includes not enabling bus parking unless the firmware tells
us to.
- Set the PCI latency timer register as this isn't always done by
the firmware.
o Remove a redundant argument from psycho_set_intr() and in this
function check the return value of bus_setup_intr(). [2]
o Let psycho_setup_intr() return ENOMEM instead of 0 when it can't
allocate memory for the interrupt wrapper stub and EINVAL instead
of 0 if it can't find the interrupt vector in the interrupt map.
o Add a workaround for a bug of the Sabre-APB-combination where it
doesn't drain DMA write data for devices behind additional PCI-PCI
bridges underneath the APB PCI-PCI bridge. This workaround (do
things necessary in order to achieve a manual drain when coherency
is required) is currently implemented in psycho_setup_intr() and
psycho_intr_stub() (for easy MFC'ing) and therefore is only applied
for interrupt handlers. This should be moved to psycho(4)-specific
bus_dma_tag_create() and bus_dmamap_sync() methods, respectively,
once this driver is converted to make use of BUS_GET_DMA_TAG(), so
the workaround is also applied for polling(4) callbacks. [3]
o Fix some minor style issues.

firmware (mainly 'pmu' and its 'lomp' dupe found in a couple of
later USII{e,i}-based machines) by checking whether a device with
the same triple of bus number, slot and function already has been
added. This is the simple yet effective approach introduced in
OpenBSD some time ago, but which has the flaw that it assumes
that the device and its dupe(s) found in the OFW device tree are
equal or at least the one encountered first is in some way the
more important one (this is the case with 'pmu' and 'lomp'; the
'pmu' node has couple of properties and children while the 'lomp'
one misses most of these). If there's ever a device/dupe pair
where we don't encounter the more important node first, we'll
probably need to introduce a quirk list in order to add the
desired device but prevent its dupe(s) from being added.

link state changes. Instead, build new speed/duplex/flow-control
settings from the values reported from PHY.
This should fix speed/duplex/flow-control mismatches between GMAC and
PHY which resulted in very poor Rx performance due to lots of
out-of-order packet delivery.

modern dual-core systems as well.
- Parse the _CST packages for each cpu and track all the states individually,
on a per-cpu basis.
- Revert to generic FADT/P_BLK based Cx control if the _CST package
is not present on all cpus. In that case, the new driver will
still support per-cpu Cx state handling. The driver will determine the
highest Cx level that can be supported by all the cpus and configure the
available Cx state based on that.
- Fixed the case where multiple cpus in the system share the same
registers for Cx state handling. To do that, added a new flag
parameter to the acpi_PkgGas and acpi_bus_alloc_gas functions that
enable the caller to add the RF_SHAREABLE flag. This flag could also be
useful to other callers (acpi_throttle?) in the tree but this change is
not yet made.
- For Core Duo cpus, both cores seems to be taken out of C3 state when
any one of the cores need to transition out. This broke the short sleep
detection logic. It is disabled now if there is more than one cpu in
the system for now as it fixed it in my case. This quirk may need to
be re-enabled later differently.
- Added support to control cx_lowest on a per-cpu basis. There is still
a generic cx_lowest to enable changing cx_lowest for all cpus with a single
sysctl and for ease of use. Sample output for the new sysctl:
dev.cpu.0.cx_supported: C1/1 C2/1 C3/57
dev.cpu.0.cx_lowest: C3
dev.cpu.0.cx_usage: 0.00% 43.16% 56.83%
dev.cpu.1.cx_supported: C1/1 C2/1 C3/57
dev.cpu.1.cx_lowest: C3

This is quite tricky situation, because we allow to open a file with
O_RDONLY|O_TRUNC. O_TRUNC modifies a file, but we actually don't open
it for writing. EISDIR is also returned when we try to open a directory
O_RDONLY|O_TRUNC, which is correct.
POSIX says that "The result of using O_TRUNC with O_RDONLY is undefined.",
we choose to accept it (Solaris did the same), that's why "to be modified"
seems more accurate to me.

Details: As a side-effect of restoring a saved FP environment,
fesetenv() overwrites the tag word, which indicates which i387
registers are in use. Normally this isn't a problem because
the calling convention requires the register stack to be empty
on function entry and exit. However, fesetenv() is inlined, so we
need to tell gcc explicitly that the i387 registers get clobbered.

New features:
1. Optional multichannel recording (32 channels on Live!, 64 channels
on Audigy).
All channels are 16bit/48000Hz/mono, format is fixed.
Half of them are copied from sound output, another half can be
used to record any data from DSP. What should be recorded is
hardcoded in DSP code. In this version it records dummy data, but
can be used to record all DSP inputs, for example..
Because there are no support of more-than-stereo sound streams
multichannell stream is presented as one 32(64)*48000 Hz 16bit mono
stream.

Fixes:
1. Do not assign negative values to variables used to index emu_cards
array. This array was never accessed when index is negative, but
Alexander (netchild@) told me that Coverity does not like it.
After this change emu_cards[0] should never be used to identify
valid sound card.
2. Fix off-by-one errors in interrupt manager. Add more checks there.
3. Fixes to sound buffering code now allows driver to use large playback
buffers.
4. Fix memory allocation bug when multichannel recording is not
enabled.
5. Fix interrupt timeout when recording with low bitrate (8kHz).
Hardware:
1. Add one more known Audigy ZS card to list. Add two cards with
PCI IDs betwen old known cards and new one.

1. Do not use ALL CAPS in messages.
