function use that for JBOD and Thunderbolt disk write command. Now
we only have one implementation in mfi.
- Fix dumping on Thunderbolt cards. Polled IO commands do not seem to
be normally acknowledged by changing cmd_status to MFI_STAT_OK.
In order to get acknowledgement of the IO is complete, the Thunderbolt
command queue needs to be run through. I added a flag MFI_CMD_SCSI
to indicate this command is being polled and to complete the
Thunderbolt wrapper and indicate the result. This flag needs to be
set in the JBOD case in case if that us using Thunderbolt card.
When in the polling loop check for completed commands.
- Remove mfi_tbolt_is_ldio and just do the check when needed.
- Fix an issue when attaching of disk device happens when a device is
already scheduled to be attached but hasn't attached.
- add a tunable to allow raw disk attachment to CAM via:
hw.mfi.allow_cam_disk_passthrough=1
- fixup aborting of commands (AEN and LD state change). Use a generic
abort function and only wait the command being aborted not both.
Thunderbolt cards don't seem to abort commands so the abort times
out.

the non-aggregate path.
I "cheated" by using some TX setup code in our HAL that isn't present
in the atheros HAL (or Linux ath9k.)
The old path for forming aggregates was:
* setup the rate control in the first descriptor;
* call chaintxdesc() on all the frames;
* call setupfirsttxdesc() on the first descrpitor in the first
frame;
* call setuplasttxdesc() on the last descriptor in the last frame.
The new path for forming aggregates looks like the non-aggregate path:
* call setuptxdesc() on the first descriptor in the first frame;
* setup the rate control in the first descriptor;
* call filltxdesc() on each descriptor in the frame;
* if it's an aggregate - call set11n_aggr_{first, middle, last} as
appropriate (see the code for a description of what is "appropriate".)
Now, this is done primarily for the AR9300 HAL - it doesn't implement
the first set of aggregate functions. It just has the older methods
and the "first/middle/last" aggregate methods. So, let's convert the
code to use these.
Note: the AR5416 HAL in FreeBSD had that code (from me, a while ago)
and a previous commit brought it up to behave the same as the AR9300
HAL routines.
There's some further tidyups to be done - specifically, avoid doing
multiple calls to the 11n descriptor functions. I shouldn't call
clr11n_aggr(), then set11n_aggr_middle(), then also set11n_aggr_first().
On (at least MIPS) the TX descriptors are in non-cachable memory and
this will cause multiple slow writes.
I'll debug/tidy that up in a future commit.
Tested:
* AR9280, STA
* AR9280/AR9160, AP
* AR9380, STA (using a local, closed source HAL, sorry!)

them, please let me know if not). Most of these are of the form:
static const struct bzzt_type {
[...list of members...]
} const bzzt_devs[] = {
[...list of initializers...]
};
The second const is unnecessary, as arrays cannot be modified anyway,
and if the elements are const, the whole thing is const automatically
(e.g. it is placed in .rodata).
I have verified this does not change the binary output of a full kernel
build (except for build timestamps embedded in the object files).

Rtld did not set FD_CLOEXEC on its internal file descriptors; therefore,
such a file descriptor may be passed to a process created by another thread
running in parallel to dlopen() or fdlopen().
No other threads are expected to be running during parsing of the hints
and libmap files but the file descriptors need not be passed to child
processes so add O_CLOEXEC there as well.
This change will break fdlopen() (as used by OpenPAM) on kernels without
F_DUPFD_CLOEXEC (added in July). Note that running new userland on old
kernels is not supported.
