af5336e30b Extend the ANI code to implement basic channel survey support.
* Always call ar5416GetListenTime()
* Modify ar5416GetListenTime() to:
  + don't update the ANI state if there isn't any ANI state;
  + don't update the channel survey state if there's no active
    channel - just to be paranoid
  + copy the channel survey results into the current sample slot
    based on the current channel; then increment the sample counter
    and sample history counter.
* Modify ar5416GetMIBCyclesPct() to simply return a HAL_SURVEY_SAMPLE,
  rather than a set of percentages.  The ANI code wasn't using the
  percentages anyway.

TODO:

* Create a new function which fetches the survey results periodically
* .. then modify the ANI code to use the pre-fetched values rather than
  fetching them again
* Roll the 11n ext busy function from ar5416_misc.c to update all the
  counters, then do the result calculation
* .. then, modify the MIB counter routine to correctly fetch a snapshot -
  freeze the counters, fetch the values, then reset the counters.

9406c902cd Add a comment about this DELAY(), I'm not sure whether it's supposed
to be for a DDR/FIFO flush or something else.

aaaca7e743 Add an AR5416 PCU DMA stop method, as a check for the AR9130 is needed.
The reference driver has a 3ms delay for the AR9130 but I'm not as yet
sure why.  From what I can gather, it's likely waiting for some FIFO
flush to occur.

At some point in the future it may be worthwhile adding a WMAC
FIFO flush here, but that'd require some side-call through to the SoC
DDR flush routines.

50e13823c8 After switching mutexes to use lwsync, they no longer provide sufficient
guarantees on acquire for the tlbie mutex. Conversely, the TLB invalidation
sequence provides guarantees that do not need to be redundantly applied on
release. Roll a small custom lock that is just right. Simultaneously,
convert the SLB tree changes back to lwsync, as changing them to sync
was a misdiagnosis of the tlbie barrier problem this commit actually fixes.

4964d80705 It was reported via email that some non-FreeBSD NFS servers
do not include file attributes in the reply to an NFS create RPC
under certain circumstances.
This resulted in a vnode of type VNON that was not usable.
This patch adds an NFS getattr RPC to nfs_create() for this case,
to fix the problem. It was tested by the person that reported
the problem and confirmed to fix this case for their server.

a607cc6d8e Fix a leak of namei lookup path buffers that occurs when a
ZFS volume is exported via the new NFS server. The leak occurred
because the new NFS server code didn't handle the case where
a file system sets the SAVENAME flag in its VOP_LOOKUP() and
ZFS does this for the DELETE case.

c6024848dd Implement the D "cpu" variable, which returns curcpu. I have chosen not
to follow the example of OpenSolaris and its descendants, which implemented
cpu as an inline that took a value out of curthread.  At certain points in
the FreeBSD scheduler curthread->td_oncpu will no longer be valid (in
particukar, just before the thread gets descheduled) so instead I have
implemented this as its own built-in variable.

fca56fb2c3 For Yukon II controllers that implement optional temperature sensor
and voltage sensor, TWSI is used to get sensor data.  msk(4) does
not monitor these sensors and interrupt for TWSI completion is
disabled by default.
However, due to unknown reason, the TWSI completion interrupt fires
and it resulted in interrupt storm.  To fix it, acknowledges the
TWSI completion interrupt if driver see the event.  Given that not
all Yukon II controllers show the issue it could be a silicon bug
which does not honor interrupt masking.

Probably the right way to address the issue is disabling automatic
TWSI cycle initiation against these sensors.  It would be even
better to implement reading voltage/temperature from the NIC but it
requires access to National LM80 through TWSI and documentation to
do that is not available yet(probably will never happen).

f13112ff78 Add placeholder methods for WMI command access (USB, perhaps SDIO later)
which will be needed for AR7010 and AR9287 USB access.

The names differ slightly from Linux and Atheros, for the sake of

A lot more work is required in order to convert the 11n HAL support to
fully support USB.

39fc714a6f If we pass down 64k - L2 hdr size + 1 to 64K L3+ data adding an ether
header will make the data go over the 64k limits announced to busdma as
maxsize and the transaction will fail.

With TSO this can result in a TCP regression due to the lost packet.

According to the data sheets ixgbe(4) 82598 and 82599 can handle up to
256k so increase the maximum.

b3bfb267cb Allow for the process information sysctls to accept a thread id in addition
to the process id.  It follows the ptrace(2) interface and allows debugging
libraries to use thread ids directly, without slow and verbose conversion
of thread id into pid.

The PGET_NOTID flag is provided to allow a specific sysctl to disallow
this behaviour.  All current callers of pget(9) have useful semantic to
operate on tid and do not need this flag.
