These describe FCC/Japan channel and DFS behaviour.
The AR9285 and later chips don't set these bits in the eeprom, the correct
behaviour is to just assume all five bits are enabled.
An optical disk may not have a TOC (e.g. for blank media) and userland
software may legitimately try to use CDIOREADTOCHEADER to find out about
the TOC.

The Atheros HAL and FreeBSD HAL share the same capabilities up
until HAL_CAP_11D, where things begin to diverge.
I'll look at tidying these up soon.
Obtained from: Atheros
* Add Howl (ar9130) to the list of chips that have DFS/BB/MAC hangs
* Don't treat unknown BB hangs as fatal; ath9k/Atheros HAL don't
treat it as such.
* Add HAL_DEBUG_DFS to the debug fields in ath_hal/ah_debug.h
The BB hang check simply loops over an observation register checking
for a stuck state engine, but it can happen under high traffic
conditions. Ath9k and the Atheros HAL simply log a debug message and
continue.
Private to FreeBSD:
* Add HAL_DEBUG_HANG to the debug fields
* Change the hang debugging to HAL_DEBUG_HANG rather than HAL_DEBUG_DFS
like in the Atheros HAL.

For now, these are equivalent macros. AR_SREV_OWL{X}_OR_LATER
will later change to exclude Howl (AR9130) in line with what
the Atheros HAL does.
This should not functionally change anything.

A quick story, which is partially documented in the commit.
The silicon revision in Linux ath9k and the Atheros HAL use an
AR_SREV_REVISION mask of 0x07.
FreeBSD's HAL uses the AR5212 AR_SREV_REVISION mask of 0x0F.
Thus the OWL silicon revisions were coming through as 0xA, 0xB,
0xC, rather than 0x0, 0x1 and 0x2.
My ath9k-sourced AR_SREV_OWL_<X> macros were thus using the wrong
silicon revision values and wouldn't correctly match.
This commit does a few things:
* Change the AR_SREV_OWL_<x> macros to use the AR_SREV_REVISION_OWL_*
values, not AR_XSREV_REVISION_OWL macros;
* Disable AR_XSREV_REVISION_OWL_* values;
* Modify the IS_5416 to properly check the MAC is OWL, rather than
potentially matching on non-OWL revisions (which shouldn't happen
unless there's a silicon revision of higher than 0x9 in a later
chip..)
* Add a couple more macros from the Atheros HAL for compatibility.
The main difference now is that the Atheros HAL defines
AR_SREV_OWL_{20,22}_OR_LATER subtly differently - it fails on all HOWL
silicon. The AR_SREV_5416_*_OR_LATER macros match on the relevant OWL
version -and- all HOWL versions, along with subsequent versions.
A subsequent commit is going to migrate the uses of AR_SREV_OWL_X_OR_LATER
to AR_SREV_5416_X_OR_LATER to match what's going on in the Atheros HAL.
There's only two uses of AR_SREV_OWL_X_OR_LATER which currently don't
apply to FreeBSD but it may do in the future.
Yes, it's all confusing!
tick driving logic to xl_tick(). Now xl_tick() handles MII tick as
well as periodic updating of statistics.
This change removes a hack used in interrupt handler where it
wanted to update statistics without driving MII tick.
picking the next available one. This may explain why xl(4) sees TX
underrun error with no queued frame. I hope this addresses a long
standing xl(4) watchdog timeout issue as well.

RX descriptor ring. Previously it returned the number of frames
that were successfully passed to upper stack which in turn means it
ignored frames that were discarded due to errors. The number of
processed frames in RX descriptor ring is used to detect whether
driver is out of sync with controller's current descriptor pointer.
Returning number of processed frames reduces unnecessary (probably
wrong) re-synchronization.
While here, remove unnecessary local variable initialization.

This ensures that mbrtowc(3) can be used directly once it has been verified
that there is no CTL* byte. Dealing with a CTLESC byte within a multibyte
character would be complicated.
The new values do occur in iso-8859-* encodings. This decreases efficiency
slightly but should not affect correctness.
Caveat: Updating across this change and rebuilding without cleaning may
yield a subtly broken sh binary. By default, make buildworld will clean and
avoid problems.
Transmission error in tun(4) is queueing error(i.e. ENOBUFS) and it
has nothing to do with collision.

server says it can support. There might be an argument
that this could be one block larger, but since NFS is
a byte granular system, I chose not to do that.

All firmwares can read it, we need to write one anyway for old OF

in favor of it.

or f_ffree fields of "struct statfs" are negative, since the
values that go on the wire are unsigned and will appear to be
very large positive values otherwise. This makes the handling
of a negative f_bavail compatible with the old/regular NFS server.
