The newer boards don't have the response field that indicates
whether the SCSI status byte is present. You have to just look to
see whether it is non-zero.
The code was looking to see whether the sense length was valid
before propagating the SCSI status byte (and sense information) up
the stack. With a status like Reservation Conflict, there is no
sense information, only the SCSI status byte. So it wasn't getting
correctly returned.
isp.c:
In isp_intr(), if we are on a 2400 or 2500 type board and
get a response, look at the actual contents of the
SCSI status value and set the RQSF_GOT_STATUS flag
accordingly so that return any SCSI status value we get. The
RQSF_GOT_SENSE flag will get set later on if there is
actual sense information returned.

If the user sends an XPT_RESET_DEV CCB, make sure to reset the
Fibre Channel Command Reference Number if we're running on a FC
controller.
We send a SCSI Target Reset when we get this CCB, and as a result
need to reset the CRN to 1 on the next command.
isp_freebsd.c:
In the XPT_RESET_DEV implementation in isp_action(), reset
the CRN if we're on a FC controller.

It is expected we will use the reg data on arm64 to enable cores so we
still need to read and store it even if it is not yet used.

every operation to retrieve the bs_cookie value almost nothing actually uses.
The bus_space struct contains a private data pointer (poorly named bs_cookie,
now renamed to bs_privdata) which is used only by a few old armv4 xscale
implementations. The bus_space functions were all defined to take this
value as the first parameter instead of the bus_space_tag_t, requiring all
the inline macro and function expansions to dereference the tag to pass it
to another function, which never uses it. Now all the functions take the tag
as the first parameter and retrieve the privdata if they need it.
Also fix a couple bus_space_unmap() implementations that were calling
kva_free() instead of pmap_unmapdev().

bits.
The motivation here is to eventually teach netisr and potentially
other networking subsystems a bit more about how RSS work queues / buckets
are configured so things have a hope of auto-configuring in the future.
* net/rss_config.[ch] takes care of the generic bits for doing
configuration, hash function selection, etc;
* topelitz.[ch] is now in net/ rather than netinet/;
* (and would be in libkern if it didn't directly include RSS_KEYSIZE;
that's a later thing to fix up.)
* netinet/in_rss.[ch] now just contains the IPv4 specific methods;
* and netinet/in6_rss.[ch] now just contains the IPv6 specific methods.
This should have no functional impact on anyone currently using
the RSS support.

accidentally enable non-existent states.
This bug was triggered if ACPI advertises the presence of a C2 state
which we fail to parse via acpi_PkgGas due to our lack of support for
FFixedHW resources, and causes an immediate panic when an attempt is
made to enter the (NULL) state.
One affected platform is the EC2 c4.8xlarge VM instance type; there
may be others.

sdhci controllers, such as the one on a Raspberry Pi, mishandle the signal
timing in high speed signaling mode, but run just fine in standard mode
with the bus running at frequencies between 25-50MHz (which shouldn't work).
This is the solution adopted by U-Boot and other OSes (linux and *BSD)
for the timeouts on Raspberry Pi boards with certain SD cards. Some
research shows that this quirk is also used on a few other boards, so the
fix is a generic quirk instead of being in the RPi-specific driver code.
This change is based on information discovered by Michal Meloun.
Required when communicating to Mac OS X USB host stack.
o Also don't set stall bit to TX pipe in device mode as seems Mac OS X
don't clears it as it should.

MCI bluetooth coexistence method for WB222.
The rest of MCI requires a bunch more work, including adding a DMA buffer
for the MCI hardware to bounce messages in/out of and handling MCI
interrupts. But the more important part here is telling the HAL
the btcoex is enabled and MCI is in use so it configures the correct
initial bluetooth parameters in the wireless NIC and configures
things like bluetooth traffic weights and such.
So, this at least gets the HAL to do some of the right things in
configuring the inital bluetooth coexistence stuff, but doesn't
actually do full btcoex. That'll take.. some effort.
Tested:
* AR9462 (WB222), STA mode
