fd16fbdd70 Updates delete_method sysctl changes to always maintain disk d_flags
DISKFLAG_CANDELETE. While this change makes this layer consistent
other layers such as UFS and ZFS BIO_DELETE support may not notice
any change made manually via these device sysctls until the device
is reopened via a mount.

Also corrected var order in dadeletemethodsysctl

3ea87cb57f Simplify in6_setscope() function to get better performance.
Currently we use interface indeces as zone IDs for link-local and
interface-local scopes, and since we don't have any tool to configure
zone IDs, there is no need to acquire the afdata lock several times per
packet only to read if_index value.
So, now in6_setscope reads zone IDs for interface-local, link-local and
global scopes without a lock.

c9bfe3d179 cxgbe(4): updates to the configuration file that controls how hardware
resources are partitioned.

- Reduce the number of virtual interfaces reserved for PF4.  This leaves
  spare room in the source MAC table and allows the driver to setup
  filters that rewrite the source MAC address.

- Reduce the number of filters and use the freed up space for the CLIP
  (Compressed Local IPv6 addresses) table.  This is a prerequisite for
  IPv6 TOE support which will follow separately in a series of commits.

6c0ef8957f Don't drop options from the third retransmitted SYN by default. If the
SYNs (or SYN/ACK replies) are dropped due to network congestion, then the
remote end of the connection may act as if options such as window scaling
are enabled but the local end will think they are not.  This can result in
very slow data transfers in the case of window scaling disagreements.

The old behavior can be obtained by setting the
net.inet.tcp.rexmit_drop_options sysctl to a non-zero value.

744c26b250 Make CTL work a little better with loading and unloading drivers.
Previously CTL would leave individual LUNs enabled in the target
driver, whether or not the port as a whole was enabled.  It would
also leave the wildcard LUN enabled indefinitely.

This change means that CTL will enable and disable any active LUNs,
as well as the wildcard LUN, when enabling and disabling a port.

Also, fix a bug that could crop up due to an uninitialized CCB
type.

ctl.c:		Before calling ctl_frontend_online(), run through
		the LUN list and enable all active LUNs.

		After calling ctl_frontend_offline(), run through
		the LUN list and disble all active LUNs.

scsi_ctl.c:	Before bringing a port online, allocate the
		wildcard peripheral for that bus.  And after taking
		a port offline, invalidate the wildcard peripheral
		for that bus.

		Make sure that we hold the SIM lock around all
		calls to xpt_action() and other transport layer
		interfaces that require it.

		Use CAM_SIM_{LOCK|UNLOCK} consistently to acquire
		and release the SIM lock.

		Update a number of outdated comments.  Some of
		these should have been fixed long ago.

		Actually do LUN disbables now.  The newer drivers
		in the tree work correctly for this as far as I
		know.

		Initialize the CCB type to CTLFE_CCB_DEFAULT to
		avoid a panic due to uninitialized memory.

43ab9660c5 Fix a bug in the device pager code that can trigger an assertion
in devfs if a particular race condition is hit in the device pager
code.

This was a side effect of change 227530 which changed the device
pager interface to call a new destructor routine for the cdev.
That destructor routine, old_dev_pager_dtor(), takes a VM object
handle.

The object handle is cast to a struct cdev *, and passed into
dev_rel().

That works in most cases, except the case in cdev_pager_allocate()
where there is a race condition between two threads allocating an
object backed by the same device.  The loser of the race
deallocates its object at the end of the function.

The problem is that before inserting the object into the
dev_pager_object_list, the object's handle is changed from the
struct cdev pointer to the object's own address.  This is to avoid
conflicts with the winner of the race, which already inserted an
object in the list with a handle that is a pointer to the same cdev
structure.

The object is then passed to vm_object_deallocate(), and eventually
makes its way down to old_dev_pager_dtor().  That function passes
the handle pointer (which is actually a VM object, not a struct
cdev as usual) into dev_rel().  dev_rel() decrements the reference
count in the assumed struct cdev (which happens to be 0), and
that triggers the assertion in dev_rel() that the reference count
is greater than or equal to 0.

The fix is to add a cdev pointer to the VM object, and use that
pointer when calling the cdev_pg_dtor() routine.

vm_object.h:	Add a struct cdev pointer to the VM object
		structure.

device_pager.c:	In cdev_pager_allocate(), populate the new cdev
		pointer.

		In dev_pager_dealloc(), use the new cdev pointer
		when calling the object's cdev_pg_dtor() routine.

78c235c99f The in6_setscope() function determines the scope zone id of an address
and embeds it into address. Inside the kernel we keep addresses with
embedded zone id only for two scopes: link-local and interface-local.

For other scopes this function is nop in most cases. To reduce an
overhead of locking, first check that address is capable for embedding.
Also, handle the loopback address before acquire the lock.

e1c562d83a Add support for triggering spectral scan upon a channel reset/change.
This is intended to support reporting FFT results during active channel
scans, for users who would like to fiddle around with writing applications
that do both FFT visualisation _and_ AP scanning.

* add a new ioctl to enable/trigger spectral scan at channel change/reset;
* set do_spectral consistently if it's enabled, so a channel set/reset
  will carry forth the correct PHY error configuration so frames
  are actually received;
* for NICs that don't do spectral scan, don't bother checking the
  spectral scan state on channel change/reset.

Tested:

* AR9280 - STA and scanning;
* AR5416 - STA, ensured that the SS code doesn't panic

43e35466de Revert r244549.
This change was originally intended to account for test kthreads under
the nvmecontrol process, but jhb indicated it may not be safe to
associate kthreads with userland processes and this could have
unintended consequences.

I did not observe any problems with this change, but my testing didn't
exhaust the kinds of corner cases that could cause problems.  It is not
that important to account for these test threads under nvmecontrol, so I
am just reverting this change for now.

On a related note, the part of this patch for <= 7.x fails compilation
so reverting this fixes that too.
