should either accept owner and owner_group strings that are just
the digits of the uid/gid or return NFS4ERR_BADOWNER.
This patch adds a sysctl vfs.nfsd.enable_stringtouid, which can
be set to enable the server w.r.t. accepting numeric string. It
also ensures that NFS4ERR_BADOWNER is returned if numeric uid/gid
strings are not enabled. This fixes the server for recent Linux
nfs4 clients that use numeric uid/gid strings by default.

This is derived from the mps(4) driver, but it supports only the 12Gb
IT and IR hardware including the SAS 3004, SAS 3008 and SAS 3108.
Some notes about this driver:
o The 12Gb hardware can do "FastPath" I/O, and that capability is included in
this driver.
o WarpDrive functionality has been removed, since it isn't supported in
the 12Gb driver interface.
o The Scatter/Gather list handling code is significantly different between
the 6Gb and 12Gb hardware. The 12Gb boards support IEEE Scatter/Gather
lists.
Thanks to LSI for developing and testing this driver for FreeBSD.

The thread that is destroying the lagg has already set sc->sc_psc=NULL when
the "ifconfig -am" thread gets to lacp_req(). It tries to dereference
sc->sc_psc and panics. The solution is for lacp_req() to check the value of
sc->sc_psc. If NULL, harmlessly return an lacp_opreq structure full of
zeros. Full details in GNATS.

The hardware can generate its own frames (eg RTS/CTS exchanges, other
kinds of 802.11 management stuff, especially when it comes to 802.11n)
and these also have PWRMGT flags. So if the VAP is asleep but the
NIC is in force-awake for some reason, ensure that the self-generated
frames have PWRMGT set to 1.
Now, this (like basically everything to do with powersave) is still
racy - the only way to guarantee that it's all actually consistent
is to pause transmit and let it finish before transitioning the VAP
to sleep, but this at least gets the basic method of tracking and
updating the state debugged.
Tested:
* AR5416, STA mode
* AR9380, STA mode

#NO_UNIVERSE. Many of these config files are important examples, but
add little to no regresive value to the intended purpose of
UNIVERSE. We now build over 120 kernels during universe. There's
really little to no value to this over building say 60 or even 30 of
them (either is still a way too big number). This is especially true
for kernels that are nothing more than including a common base and
adding a static DTB file. Start by pruning 1/3 of the arm kernels that
add little regresion value.

into your kernel, however, it cannot be a list. We have no mechanism
in the kernel for picking one, so that doesn't make sense and will
result in a compile-time error.
The changes how TRIM requests are generated to use ZIO_TYPE_FREE + a priority
instead of ZIO_TYPE_IOCTL, until processed by vdev_geom; only then is it
translated the required geom values. This reduces the amount of changes
required for FREE requests to be supported by the new IO scheduler. This
also eliminates the need for a specific DKIOCTRIM.
Also fixed FREE vdev child IO's from running ZIO_STAGE_VDEV_IO_DONE as part
of their schedule.
As the new IO scheduler can result in a request to execute one type of IO to
actually run a different type of IO it requires that zio_trim requests are
processed without holding the trim map lock (tm->tm_lock), as the free request
execute call may result in write request running hence triggering a
trim_map_write_start call, which takes the trim map lock and hence would result
in recused on no-recursive sx lock.

Instead of rereading VPD pages on every device open, do it only on initial
device probe, and in cases when device reported via UNIT ATTENTIONs that
something has changed. Capacity is still rereaded on every open because
it is more critical for operation and more probable to change in run time.
On my tests with Intel 530 SSDs on mps(4) HBA this change reduces time
GEOM needs to retaste the device (that includes few open/close cycles)
from ~150ms to ~30ms.

fixes and beacon programming / debugging into the ath(4) driver.
The basic power save tracking:
* Add some new code to track the current desired powersave state; and
* Add some reference count tracking so we know when the NIC is awake; then
* Add code in all the points where we're about to touch the hardware and
push it to force-wake.
Then, how things are moved into power save:
* Only move into network-sleep during a RUN->SLEEP transition;
* Force wake the hardware up everywhere that we're about to touch
the hardware.
The net80211 stack takes care of doing RUN<->SLEEP<->(other) state
transitions so we don't have to do it in the driver.
Next, when to wake things up:
* In short - everywhere we touch the hardware.
* The hardware will take care of staying awake if things are queued
in the transmit queue(s); it'll then transit down to sleep if
there's nothing left. This way we don't have to track the
software / hardware transmit queue(s) and keep the hardware
awake for those.
Then, some transmit path fixes that aren't related but useful:
* Force EAPOL frames to go out at the lowest rate. This improves
reliability during the encryption handshake after 802.11
negotiation.
Next, some reset path fixes!
* Fix the overlap between reset and transmit pause so we don't
transmit frames during a reset.
* Some noisy environments will end up taking a lot longer to reset
than normal, so extend the reset period and drop the raise the
reset interval to be more realistic and give the hardware some
time to finish calibration.
* Skip calibration during the reset path. Tsk!
Then, beacon fixes in station mode!
* Add a _lot_ more debugging in the station beacon reset path.
This is all quite fluid right now.
* Modify the STA beacon programming code to try and take
the TU gap between desired TSF and the target TU into
account. (Lifted from QCA.)
