87aa6825ff cxgbe/tom: Basic CLIP table management.
This is the Compressed Local IPv6 table on the chip.  To save space, the
chip uses an index into this table instead of a full IPv6 address in
some of its hardware data structures.

For now the driver fills this table with all the local IPv6 addresses
that it sees at the time the table is initialized.  I'll improve this
later so that the table is updated whenever new IPv6 addresses are
configured or existing ones deleted.

f62c1a47d6 Alike to r242314 for GRAID make GRAID3 more aggressive in marking volumes
as clean on shutdown and move that action from shutdown_pre_sync stage to
shutdown_post_sync to avoid extra flapping.

ZFS tends to not close devices on shutdown, that doesn't allow GEOM RAID
to shutdown gracefully.  To handle that, mark volume as clean just when
shutdown time comes and there are no active writes.

7f441ef267 cxgbe/tom: Miscellaneous updates for TOE+IPv6 support (more to follow).
- Teach find_best_mtu_idx() to deal with IPv6 endpoints.

- Install correct protosw in offloaded TCP/IPv6 sockets when DDP is
  enabled.

- Move set_tcp_ddp_ulp_mode to t4_tom.c so that t4_tom.h can be included
  without having to drag in t4_msg.h too.  This was bothering the iWARP
  driver for some reason.

eb23ab3120 Update sigcode to use both the current ABI and FreeBSD's version of the
ARM EABI syscall calling convention.

The current ABI encodes the syscall number in the instruction. This causes
issues with the thumb mode as it only has 8 bits to encode this value and
we have too many system calls and by using a register will simplify the
code to get the syscall number in the kernel.

With the ARM EABI we reuse the Linux calling convention by storing the
value in r7. Because of this we use both methods to encode the syscall
number in this function.

10b4bb0b33 Add a trivial comment to record the proper commit log for r245407:
Set the v_hash for a new vnode in the getnewvnode() to the value
calculated based on the vnode structure address.  Filesystems using
vfs_hash_insert() override the v_hash using the standard formula of
(inode_number + mnt_hashseed).  For other filesystems, the
initialization allows the vfs_hash_index() to provide useful hash too.

603f963e56 The current default size of the nullfs hash table used to lookup the
existing nullfs vnode by the lower vnode is only 16 slots.  Since the
default mode for the nullfs is to cache the vnodes, hash has extremely
huge chains.

Size the nullfs hashtbl based on the current value of

  Implement a MIPS FDT PIC decode routine to use when no PIC has been

  the on-board CP0 interrupt management parts on the MIPS).  If the
  soc bus in a MIPS DTS file is declared as "mips4k,cp0"-compatible,
  then this will be enabled.  This is sufficient to allow IRQs to be

f404e02afd Remove not very useful printf, that can be too chatty.
ASUS P8Z77-V board reports _AC2, _AC3 and _AC4 setpoints as 0C.  With active
cooling already automatically set to _AC2, that still caused driver to print
two useless lines about temperature above _AC3 and _AC4 every ten seconds.
Three setponts of 0C is probably a board bug, but the same spam could happen
also in correct case if system is runnign not with the lowest cooling level.

290a1ba9a4 The current ZFS code expects ddt_zap_count to always succeed by asserting
the underlying zap_count() to return no errors.  However, it is possible
that the pool reaches to such a state where zap_count would return error,
leading to panics when a pool is imported.

This commit changes the ddt_zap_count to return error returned from
zap_count and handle the error appropriately.  With this change, it's now
possible to let zpool rollback damaged transaction groups and import the
pool.

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
