The macro which I incorrectly copied into ah_internal.h assumed
that it'd be called with an AR_SREV_MERLIN_20() check to ensure
it was only enabled for Merlin (AR9280) silicon revision 2.0 or
later.
Trouble is, the 5GHz fast clock EEPROM flag is only valid for
EEPROM revision 16 or greater; it's assumed to be enabled
by default for Merlin rev >= 2.0. This meant it'd be incorrectly
set for AR5416 and AR9160 in 5GHz mode.
This would have affected non-default clock timings such as SIFS,
ACK and slot time. The incorrect slot time was very likely wrong
for 5ghz mode.
* Modify AR_SREV_MERLIN_20() to match the Atheros/Linux ath9k behaviour -
its supposed to match Merlin 2.0 and later Merlin chips.
AR_SREV_MERLIN_20_OR_LATER() matches AR9280 2.0 and later chips
(AR9285, AR9287, etc.)
operate on one type of filesystem, mention this.
While here, capitalise the use of "UFS" in growfs.8 to match other uses of
the term in other man pages.

an attacker with root access to the jail can create a setuid binary for
their own use in the host environment (if they also have this access),
thus breaking root in the host.
This exploit is impossible if the jail's files are not world-readable.
Add instructions to the man page on how to create a jail with the
correct permissions set.

- instead of calling iwn_plcp_signal() for every frame, map the expected
value directly within wn->ridx
- concat plcp, rflags and xrflags, there is no clean byte boundary within
the flags, for example the antenna setting uses bit 6, 7 and 8

fnmatch(3).)

always using first key.
We need to support providers created with this bug, so set special
G_ELI_FLAG_FIRST_KEY flag for GELI provider in integrity mode with version
smaller than 6 and pass the CRD_F_KEY_EXPLICIT flag to opencrypto only if
G_ELI_FLAG_FIRST_KEY doesn't exist.

It isn't used yet; ar5416GetWirelessModes() needs to be taught
about this rather than assuming HT20/HT40 is available.
This seems to make the AR9160 behave better during heavy scanning,
where before it'd hang and require a hard reset to recover.

modifying AR_DIAG_SW.
There's a hardware workaround which sets disabling some errors
early at startup and clears said bits before the PCU begins
receiving - it does this to avoid RX descriptor status errors.
It's possible these bits aren't being completely properly twiddled
in all instances; but in particular if the diag_reg HAL variable
is set it won't be setting these bits correctly. I'll review this
at some point.
* Disable multicast search on mac address and key id - the driver
doesn't use it at the moment and thus adhoc may be broken for
merlin and later.
* Change this to be for Merlin 1.0 (which from what I understand
wasn't ever publicly released) to be more correct.
Apparently all three RX chains need to be enabled before initial calibration
is done, even if only two are configured.
Reorder the alt chain swap bit to match what the Atheros HAL is doing.
