mount point crossings correctly. It was testing the wrong flag.
Also, try harder to make sure that the fsid is different than
the one assigned to the client mount point, by hashing the
server's fsid (just to create a different value deterministically)
when it is the same.

details of each rman header, but not the contents of all rman structures
in the system. This is especially useful on platforms where some rmans
have many thousands of entries in rmans, making scrolling through the
output of "show all rman" impractical. Individual rmans can then be viewed
including their contents with "show rman 0xaddr" as usual.

- make SATA SIMs announce capabilities to handle SDB with Notification bit;
- make PMP driver honor this SIMs capability;
- make SATA XPT to negotiate and enable this feature for ATAPI devices.
This feature allows supporting SATA ATAPI devices to inform system about
some events happened, that may require attention. In my case this allows
LG GH22LS50 SATA DVR-RW drive to report tray open/close events. Events
reported to CAM in form of AC_SCSI_AEN async. Further they could be used
as a hints for checking device status and reporting media change to upper
layers, for example, via spoiling mechanism of GEOM.
diversity.
This is bit dirty and likely should be revised at a later date,
with an eye to unifying/tidying up the whole diversity setup
and allowing developers to do "tricky stuff" as they desire.
For now, this works.
* add a new method, specifically for doing per-RX packet
antenna diversity
* set that HAL method only if it's Kite and a Kite chip that
does diversity.
* add a diversity flag to the HAL debugging section
* add a check to make sure the kite diversity code doesn't run
on boards that don't require it, as not all Kite chips will
implement it.
* add some debug statements when the diversity code makes
changes to the antenna diversity/combining setup.
controller port readiness (that should set just after PHY ready signal),
reduce wait time from 10s to 1s before trying more aggressive reset method.
This should improve system responsibility in some failure conditions.
Note: this HAL currently only supports the AR9285.
From Linux ath9k:
The problem is that when the attenuation is increased,
the rate will start to drop from MCS7 -> MCS6, and finally
will see MCS1 -> CCK_11Mbps. When the rate is changed b/w
CCK and OFDM, it will use register desired_scale to calculate
how much tx gain need to change.
The output power with the same tx gain for CCK and OFDM modulated
signals are different. This difference is constant for AR9280
but not AR9285/AR9271. It has different PA architecture
a constant. So it should be calibrated against this PA
characteristic.
The driver has to read the calibrated values from EEPROM and set
the tx power registers accordingly.
the username-for-accounting field (P), not the username-for-headerpage (L).
These are usually the same value, except that control files do not have
the username-for-headerpage field if the user has requested no header page.
- Also rename the cji_username field to cji_headruser, to make it clear that
the value should only be used for the header page. (aka banner page)

not believe that these leaks had a practical impact,
since the situations in which they would have occurred
would have been extremely rare.

bit more reliable now.

Note that applications has to pass HN_IEC_PREFIXES to use this
