1) s/mi/mfi/ in FreeBSD ioctl path
2) add in "\n" on various failure messages
3) cap the length of time to abort an AEN command
4) fix passing sense data back to user to make Dell's Linux firmware
upgrade tool happy.
5) bump the MFI_POLL_TIMEOUT_SECS from 10s to 50s since the
firmware flash command can take ~40s to return.
This is some clean-up and enables RAID firmware to updated via Dell's
tool. Note Dell's tool requires the updates to the Linux emulator
that has been done in -current with TLS etc.
I need to discuss with scottl how to better submit mfi commands to
the firmware via the ioctl path so we don't do it in polled mode.
after calling mfi_mapcmd is no longer needed, so long as the MFI_CMD_POLLED
flag is set. This change eliminates the possibility of a polled command
getting posted twice to the driver. This is turn fixes panics on shutdown
when INVARIANTS is set.

- Add a translation so the Linux ioctl's don't conflict with
the FreeBSD definition.
- Assume Linux 32bit emulation on amd64.
This was tested on i386 and amd64 with the 32bit Linux MegaCli.
Eventually we should do a 32bit native FreeBSD translation app.
- Fix the locking protocol to eliminate races between normal I/O and AENs.
- Various small improvements and usability tweaks.

AEN. This makes the boot messages cleaner. I now know how this
structure works so I can implement it versus guessing. Remove the
not ready type code since it is ready now.
I added the time stamp/locale/class so people can parse messages better.
Create a sysctl so that we can set the locale/class level.
the description so we don't have to do any more queries. Disable the
event query code until it figured out since but it is similar to the
AEN detail so we should be able to get that working.
- 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.

Saab for helping to track this down. Fix a error with 32bit DMA size
calculation that seemed to be harmless. Add a few micro-optimizations while
I'm here.
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.
