controller, but make it optional.
After a problem report from Andrew Boyer, it looks like the LSI
chip may have issues (the watchdog timer fired) if too many aborts
are sent down to the chip at the same time. We know that task
management commands are serialized, and although the manual doesn't
say it, it may be a good idea to just send one at a time.
But, since I'm not certain that this is necessary, add a tunable
and sysctl variable (hw.mps.%d.allow_multiple_tm_cmds) to control
the driver's behavior.
mps.c: Add support for the sysctl and tunable, and add a
comment about the possible return values to
mps_map_command().
mps_sas.c: Run all task management commands through two new
routines, mpssas_issue_tm_request() and
mpssas_complete_tm_request().
This allows us to optionally serialize task
management commands. Also, change things so that
the response to a task management command always
comes back through the callback. (Before it could
come via the callback or the return value.)
mpsvar.h: Add softc variables for the list of active task
management commands, the number of active commands,
and whether we should allow multiple active task
management commands. Add an active command flag.
mps.4: Describe the new sysctl/loader tunable variable.

I'm unable to reproduce the race described in comment anymore and also the
comment is incorrect - localfd represents local component from configuration
file, eg. /dev/da0 and not HAST provider.

A new function prep_devname() sanitizes a device name by removing
leading and redundant sequential slashes. The function returns an error
for names which already exist or are considered invalid.
A new flag MAKEDEV_CHECKNAME for make_dev_p(9) and make_dev_credf(9)
indicates that the caller is prepared to handle an error related to the
device name. An invalid name triggers a panic if the flag is not
specified.
Document the MAKEDEV_CHECKNAME flag in the make_dev(9) manual page.

generate link state change interrupt for non-5788 controllers. The
interrupt handler may or may not detect link state attention as
status block wouldn't be updated when an interrupt was generated
with BGE_MISC_LOCAL_CTL register. All controllers except 5700 and
5788 should use host coalescing mode register to trigger an
interrupt.

versions of controller support different number of ring control
blocks such that adjust code a bit to access known number of
send/receive ring control blocks. Previously bge(4) blindly
accessed 16 send/receive RCBs. Also move initializing standard
receive producer ring producer index, jumbo receive producer ring
producer index and mini receive producer ring producer index to
the end of each receive producer ring initialization.
Do not assume mini receive producer ring is available only when
controller has jumbo frame capability, instead explicitly check
ASIC version BCM5700 to disable mini receive producer ring.
Additionally always enable send ring 0 regardless of controller
versions. Previously bge(4) didn't enable send ring 0 if controller
is BGE_IS_5705_PLUS. Becase bge(4) need 1 send ring to send frames
at least, I have no idea how it would have worked so far.

makes on FreeBSD/pc98. The need for this hack has passed. If you are
one of the rare people that may need this, then you should setenv
MACHINE=pc98 as a workaround.
Make "clang -print-multi-os-directory" return "." on amd64, matching
gcc's behaviour. This is needed because some ports use the option to
determine the installation directory for their libraries.
