610f2ef365 Update the MFI driver to support new "1078" series of hardware. This 
includes the upcoming Dell PERC6 series.  Many thanks to LSI for
contributing this code.

5be25877a1 Add in a couple of things: 
-	In the ioctl path let command get queued up and return
	when complete _without_ blocking the driving waiting for
	the response.  This way the driver doesn't "lock up" for
	~30s during a flash command.  Submitted by scottl.
      -	Add a guard so that if a DCMD of 0 is sent down the ioctl
	path don't send it to the controller.  Return with a
	status of OK.  This is a little strange since MegaCli
	doesn't seem to like something and will issue some DCMD
	of 0.  This doesn't happen under Linux.  So the emulation
	needs to be improved but I'm not sure what.  Another strange
	thing is that when a DCMD of 0 gets issued under i386 the
	controller returns OK but in amd64 the context is messed
	up.
      -	Add a guard so the context has to be with-in the legal
	limit so we get a reasonable error assertion versus random
	panic.

It's going to be a challenge to figure out why MegaCli is not totally
happy and then sends some bogus commands.  This means that flashing
firmware via the Linux tool won't work since it generates a DCMD of
0 when it should be opening the firmware for a flash update.  Without
this problem flashing works fine.  This means there is no publicly
available tool to upgrade the RAID firmware under FreeBSD right now.

I plan to MFC all of the mfi changes to 6.X shortly.  This might not
include the SCSI pass-through changes.

array Id's to FreeBSD device names.

c0b332d17a Instead of using scsi probes to do device discovery, use the firmware 
commands to grab the device listing.  This resolves issues using
multiple volumes, where each volume was actually internally pointing
to target 0.

741367d5a5 Add in a bunch of things to the mfi driver: 
- Linux ioctl support, with the other Linux changes MegaCli
	will run if you mount linprocfs & linsysfs then set
	sysctl compat.linux.osrelease=2.6.12 or similar.  This works
	on i386.  It should work on amd64 but not well tested yet.
	StoreLib may or may not work.  Remember to kldload mfi_linux.
      - Add in AEN (Async Event Notification) support so we can
	get messages from the firmware when something happens.
	Not all messages are in defined in event detail.  Use
	event_log to try to figure out what happened.
      - Try to implement something like SIGIO for StoreLib.  Since
	mrmonitor doesn't work right I can't fully test it.  StoreLib
	works best with the rh9 base.  In theory mrmonitor isn't
	needed due to native driver support of AEN :-)
Now we can configure and monitor the RAID better.

2e21a3ef7e Add a driver for the new LSI MegaRAID SAS controller family. The 'MFI' name 
is derived from the phrase 'MegaRAID Firmware Interface' used by LSI.  This
driver provides a block interface to logical disks on the card and a minimal
management device.  It is MPSAFE, INTR_FAST, and 64-bit capable.

Thanks to Dell for providing hardware to test with and IronPort for
sponsoring the work.
