making the use of sc_hwmap to do direct mapping impractical. Switch to
indexing by the rate index instead of the rate code and adjust associated
state and logic appropriately. This has several benefits including
simplification of the led code.
o fix radiotap capture of HT rates
o fix conditional compilation of HT radiotap support to be based on the
hal having 5416 support; not the ABI version as hal builds may or may
not include 5416 support
o update tx rssi data only when an ACK was received
o return tx rssi from sampled data instead of the last frame
o track noise floor
o return rx rssi and noise floor (was broken)
o pass country code, outdoor indication, and ecm mode into the hal
when requesting a channel list
o add a console msg when regulatory setup fails
o add placeholder code to map between Atheros sku's and 802.11 sku's
that handles only the debug country code used to unlock the full
channel list (to be used only for debugging)
o fix multiple instances of mismapping the 802.11 location to the
outdoor indication (anywhere may be outdoor also)
in sta and adhoc modes; this should've been done forever ago as most all
drivers use this hook to set per-station transmit parameters such as for
tx rate control
o adjust drivers to remove explicit calls to the driver newassoc method
a) Need for EEOR mode to take the min of the socket buffer size and the
add more threshold, otherwise if you are so silly as to set a send
buf size less than the add-more you could block forever in eeor mode.
b) We were incorrectly using the sysctl vs the calculated value. This
causes us to block forever if the addmore theshold is larger than
then the socket buffer size.
- If we send EXACTLY the size left in the send buffer
and then send again, we end up with exactly 0 bytes and
don't hit the pre-block code to wait for more space.
- If we fall into the loop with our max_len == 0 (the bug
above) we then call in to copy out the data, setup the length
of the waiting to transmit data to 0 and call the mbuf copy routine
which 0 indicates copy all the data to the mbuf chain.. which it
does. This then leaves a "stuck" message on the stream queue with
its size exactly 0 bytes but all the data there and thus nothing
left in the uio structure. We then reach a stuck forever state
never being able to send data.
control logic and policy registration remaining in that file, and access
control checks broken out into other files by class of check.

The cn_unit and cn_tp fields don't seem to be used anywhere. Some
drivers set them, while others don't. Just remove them, in an attempt to
make our consdev code a little easier to understand.
certain ATA-6 drives including CF cards.
The IDE geometry of the PC98 is calculated from the drive capacity.
In addition to the algorithm in NEC BIOS, a variety of algorithms are
provided by 3'rd party boards and BIOS hacks. This change has
implemented the three algorithms: IDE BIOS compatible mode, SCSI BIOS
compatible mode and same way as the previous version. The tunable
machdep.ad_geom_method selects the algorithm.
I have been using this change for a year with CF cards.

Due to the nature of the beast it causes lot of unproductive overhead. This
is especially bad when running SMP kernel on VMWare with several virtual
processors - idle FreeBSD guest with SMP kernel takes 150% host CPU time on my
dual-core MacBook Pro when I am enabling two virtual CPUs, making even host
not very usable. Detect when we are running in the sandbox and reduce HZ
to 10 (can be adjusted via VM_HZ in the kernel config) in such cases. This
brings host CPU usage of idle FreeBSD/SMP on two virtual processors down
to 10%.
Detect most popular VM platforms out there - VMWare, Parallels, VirtualBox
and VirtualPC.

to set the initial PIO mode instead of assuming PIO4. There are still a few
nagging issues:
- There are some problems with 64 K DMA transfers waiting on lower level
changes.
- ATAPI DMA is broken on Marcel's Mac Mini because we need an ATA SELECT hook
propagated up to individual drivers for hardware without timing registers for
each ATA channel.

This allows policies to label reassembly queues, perform access
control checks when matching fragments to a queue, update a queue
label when fragments are matched, and label the resulting
reassembled datagram.

(unless explicitly locked to mode 11b) so when we join the bss the
channel attached to the scan cache entry may need to be demoted.
o demote to 11b if the ap is advertising 11b rates
o skip the ap if it's 11b but we're locked to 11g (could consider this
advisory but for now treat it as mandatory)
o handle an odd edge case, if there is a fixed transmit rate for 11g
then the rate check against the 11b ap will fail, try to demote to
11b and retry the rate check

unnecessary casts.
