3631c6382f Implement media change notification for DA and CD removable media devices.
It includes three parts:
 1) Modifications to CAM to detect media media changes and report them to
disk(9) layer. For modern SATA (and potentially UAS) devices it utilizes
Asynchronous Notification mechanism to receive events from hardware.
Active polling with TEST UNIT READY commands with 3 seconds period is used
for incapable hardware. After that both CD and DA drivers work the same way,
detecting two conditions: "NOT READY: Medium not present" after medium was
detected previously, and "UNIT ATTENTION: Not ready to ready change, medium
may have changed". First one reported to disk(9) as media removal, second
as media insert/change. To reliably receive second event new
AC_UNIT_ATTENTION async added to make UAs broadcasted to all periphs by
generic error handling code in cam_periph_error().
 2) Modifications to GEOM core to handle media remove and change events.
Media removal handled by spoiling all consumers attached to the provider.
Media change event also schedules provider retaste after spoiling to probe
new media. New flag G_CF_ORPHAN was added to consumers to reflect that
consumer is in process of destruction. It allows retaste to create new
geom instance of the same class, while previous one is still dying.
 3) Modifications to some GEOM classes: DEV -- to report media change
events to devd; VFS -- to handle spoiling same as orphan to prevent
accessing replaced media. PART class already handles spoiling alike to
orphan.

0f4a46b376 Shuffle the rate control call to be consistent with non-aggregate TX.
The correct ordering for non-aggregate TX is:

* call ath_hal_setuptxdesc() to setup the first TX descriptor complete
  with the first TX rate/try count;
* call ath_hal_setupxtxdesc() to setup the multi-rate retry;
* .. or for 802.11n NICs, call ath_hal_set11nratescenario() for MRR and
  802.11n flags;
* then call ath_hal_filltxdesc() to setup intermediary descriptors
  in a multi-descriptor single frame.

The call to ath_hal_filltxdesc() routines seem to correctly (consistently?)
handle the intermediary descriptor flags, including copying the rate
control information to the final descriptor in the frame.  That's used
by the rate control module rather than the hardware.

Tested:

* Only on AR9280 STA mode, however it should work on other chips in
  both STA and AP mode.

7ef7f613c2 Fix breakage introduced in r238824 - correctly calculate the descriptor
wrapping.

The previous code was only wrapping descriptor "block" boundaries rather
than individual descriptors.  It sounds equivalent but it isn't.

r238824 changed the descriptor allocation to enforce that an individual
descriptor doesn't wrap a 4KiB boundary rather than the whole block
of descriptors.  Eg, for TX descriptors, they're allocated in blocks
of 10 descriptors for each ath_buf (for scatter/gather DMA.)

5e5c0e7980 Hardcode the loopback rx/tx checkum options for IPv6 to on without
checking. This allows the FreeBSD 9.1 release process to move forward.
Work around the problem that loopback connections to local addresses
not on loopback interfaces and not on interfaces w/ IPv6 checksum offloading
enabled would not work.
A proper fix to allow us to disable the "checksum offload" on loopback
for testing, measurements, ... as we allow for IPv4 needs to put in
place later.

MISC CHANGES

Add a new async event- ISP_TARGET_NOTIFY_ACK, that will guarantee
eventual delivery of a NOTIFY ACK. This is tons better than just
ignoring the return from isp_notify_ack and hoping for the best.

Clean up the lower level lun enable code to be a bit more sensible.

Fix a botch in isp_endcmd which was messing up the sense data.

Fix notify ack for SRR to use a sensible error code in the case
of a reject.

Clean up and make clear what kind of firmware we've loaded and
what capabilities it has.
-----------
FULL (252 byte) SENSE DATA

In CTIOs for the ISP, there's only a limimted amount of space
to load SENSE DATA for associated CHECK CONDITIONS (24 or 26
bytes). This makes it difficult to send full SENSE DATA that can
be up to 252 bytes.

Implement MODE 2 responses which have us build the FCP Response
in system memory which the ISP will put onto the wire directly.

On the initiator side, the same problem occurs in that a command
status response only has a limited amount of space for SENSE DATA.
This data is supplemented by status continuation responses that
the ISP pushes onto the response queue after the status response.
We now pull them all together so that full sense data can be
returned to the periph driver.

This is supported on 23XX, 24XX and 25XX cards.

This is also preparation for doing >16 byte CDBs.

-----------
FC TAPE

Implement full FC-TAPE on both initiator and target mode side.  This
capability is driven by firmware loaded, board type, board NVRAM
settings, or hint configuration options to enable or disable. This
is supported for 23XX, 24XX and 25XX cards.

On the initiator side, we pretty much just have to generate a command
reference number for each command we send out. This is FCP-4 compliant
in that we do this per ITL nexus to generate the allowed 1 thru 255
CRN.

In order to support the target side of FC-TAPE, we now pay attention
to more of the PRLI word 3 parameters which will tell us whether
an initiator wants confirmed responses. While we're at it, we'll
pay attention to the initiator view too and report it.

On sending back CTIOs, we will notice whether the initiator wants
confirmed responses and we'll set up flags to do so.

If a response or data frame is lost the initiator sends us an SRR
(Sequence Retransmit Request) ELS which shows up as an SRR notify
and all outstanding CTIOs are nuked with SRR Received status. The
SRR notify contains the offset that the initiator wants us to restart
the data transfer from or to retransmit the response frame.

If the ISP driver still has the CCB around for which the data segment
or response applies, it will retransmit.

However, we typically don't know about a lost data frame until we
send the FCP Response and the initiator totes up counters for data
moved and notices missing segments. In this case we've already
completed the data CCBs already and sent themn back up to the periph
driver.  Because there's no really clean mechanism yet in CAM to
handle this, a hack has been put into place to complete the CTIO
CCB with the CAM_MESSAGE_RECV status which will have a MODIFY DATA
POINTER extended message in it. The internal ISP target groks this
and ctl(8) will be modified to deal with this as well.

At any rate, the data is retransmitted and an an FCP response is
sent. The whole point here is to successfully complete a command
so that you don't have to depend on ULP (SCSI) to have to recover,
which in the case of tape is not really possible (hence the name
FC-TAPE).

051d6b64cd Merge FreeBSD/beri Perforce change @211945 to head:
Modify MIPS page table entry (PTE) initialisation so that cachability
bits are set only once, using is_cacheable_mem() to determine what
caching properties are required, rather than also unconditionally
setting PTE_C_CACHE in init_pte_prot().  As PTE_C_CACHE |
PTE_C_UNCACHED == PTE_C_CACHE, this meant that all userspace memory
mappings of device memory (incorrectly) used caching TLB entries.

This is arguably not quite what we want, even though it is (more)
consistent with the MIPS pmap design: PTE caching properties should
be derived from machine-independent page table attributes, but this
is a substantially more complex change as the MIPS pmap doesn't yet
know about page attributes, causing it to ignore requests by device
drivers that want uncached userspace memory mappings as they
describe memory-mapped FIFOs or shared memory with a device not
participating in the cache coherence scheme.

This fixes cacheability issues (specifically, undesired and
unrequested caching) seen in userspace memory mappings of Avalon SoC
bus device memory on BERI MIPS.

614e309803 Pull the tier-2 card and change the sparc64 ZFS loader to no longer probe
all diskN aliases for providers (which more or less corresponds to how the
x86 version behaves) but instead probe only those listed in the boot-device
OFW environment variable. This has the following advantages:
- avoids otherwise unavoidable OFW warnings about failures to open disks
  for which aliases exist but no actual hardware is connected
- avoids issues due to different diskN naming schemes
- aligns us with Solaris
