and:
o Associate AC97_MIX_AUXOUT with SOUND_MIXER_OGAIN rather than
SOUND_MIXER_MONITOR.
o Add ac97_fix_tone to remove tone controls from mixer if invalid.
are all bogus, and the cards that don't decode things quite right
often have hundreds of them. This will fix starvation of small dmesg
buffers and allow better debugging to happen. I thought about adding
an override, but there is such a thing as too many knobs. :-)
- Fix up TX speed changes.
- Make mpi-350 cards sort-of work with new firmware. It RXs okay but TXs
only work for about 14 packets then fails to get an interrupt. The
TX watchdog fires. It has been reported that my hack for now doesn't
break cards with the older firmware. It appears my card has lost
the ability to RX or TX at all but other peoples cards work. I assume
it got damaged in tansport.

count handling of station entries in hostap mode:
Input path:
o driver is now expected to find the node associated with the
sender of a received frame; use ic_bss if none is located
o driver passes the (referenced) node into ieee80211_input for
use within the wlan module and is responsible for cleaning up
on return
o the antenna state is no longer passed up with each frame; this
is now considered driver-private state and drivers are responsible
for keeping it in the driver-private part of a node
Output path:
Revamp output path for management frames to eliminate redundant
locking that causes problems and to correct reference counting
bogosity that occurs when stations are timed out due to inactivity
(in AP mode). On output the refcnt'd node is stashed in the pkthdr's
recvif field (yech) and retrieved by the driver. This eliminates
an unref/ref scenario and related node table unlock/lock due to the
driver looking up the node. This is particularly important when
stations are timed out as this causes a lock order reversal that
can result in a deadlock. As a byproduct we also reduce the overhead
for sending management frames (minimal). Additional fallout from
this is a change to ieee80211_encap to return a refcn't node for
tieing to the outbound frame. Node refcnts are not reclaimed until
after a frame is completely processed (e.g. in the tx interrupt
handler). This is especially important for timed out stations as
this deref will be the final one causing the node entry to be
reclaimed.
Additional semi-related changes:
o replace m_copym use with m_copypacket (optimization)
o add assert to verify ic_bss is never free'd during normal operation
o add comments explaining calling conventions by drivers for frames
going in each direction
o remove extraneous code that "cannot be executed" (e.g. because
pointers may never be null)
quietly discard them; this just permits them to be collected with bpf)
o add a counter for the number of rate control frames discarded when not in
monitor mode
o move the rx "too short" statistic in the stat structure so non-error rx stats
are together (NB: ABI change to apps that collect stats via driver ioctl)
mistakes (this mistake was not an issue because the length is only used to
decide whether or not to allocate a cluster)
o while here, move a beacon length comment to the "right place"
present, and non-zero when it is (or may be) absent. The test
cbb_child_present was backwards. However, typical usage in the tree
would cause it to do the right thing because the card really wasn't
there the OK flag would be turned on.
Also, assume that if any of these bits are turned on we don't have a
card, rather than requiring both of them in the suspend/resume
routines.
Noticed by: cognet
to what is in NetBSD. I have a few cards that tickles this bug, and
this just keeps us from panicing. It doesn't actually fix the problem
(that will happen once I figure out why some cards hate the address
their CIS is mapped to high memory).
A timecounter will be selected when registered if its quality is
not negative and no less than the current timecounters.
Add a sysctl to report all available timecounters and their qualities.
Give the dummy timecounter a solid negative quality of minus a million.
Give the i8254 zero and the ACPI 1000.
The TSC gets 800, unless APM or SMP forces it negative.
Other timecounters default to zero quality and thereby retain current
selection behaviour.
Correctly handle additional disks without BIOS partition tables.
Previously, vinum_scandisk stopped scanning additional disks for
native partitions after any good partition was found. This applies
to all platforms, but was a particular problem on systems without
BIOS partition tables.

the hardware mutex if it is held. Re-add calls to Enable/Clear fixed events.
This is not known to have caused problems. Bug symptoms might have included
instability after an aborted suspend attempt or power/sleep buttons not
being enabled.
