cards. LSI has been maintaining this driver outside of the FreeBSD
tree. It overlaps support of ThunderBolt and Invader cards that mfi(4)
supports. By default mfi(4) will attach to cards. If the tunable:
hw.mfi.mrsas_enable=1
is set then mfi(4) will not probe and attach to these newer cards and
allow mrsas(4) to attach. So by default this driver will not effect
a FreeBSD system unless mfi(4) is removed from the kernel or the
tunable is enabled.
mrsas(4) attaches disks to the CAM layer so it depends on CAM and devices
show up as /dev/daX. mfiutil(8) does not work with mrsas. The FreeBSD
version of MegaCli and StorCli from LSI do work with mrsas. It appears
that StorCli only works with mrsas. MegaCli appears to work with mfi(4)
and mrsas(4).
It would be good to add mfiutil(4) support to mrsas, emulations modes,
kernel logging, device aliases to ease the transition between mfi(4)
and mrsas(4).
Style issues should be resolved by LSI when they get committers approved.
The plan is get this driver in FreeBSD 9.3 to improve HW support.
Thanks to LSI for developing, testing and working with FreeBSD to
make this driver co-exist in FreeBSD. This improves the overall
support of MegaRAID SAS.

/usr/src and not others that use the bsd.*.mk files. Specifically
don't install src.opts.mk so we can catch when it 'leaks' into
bsd.*.mk again and have there be errors when this happens. Future
commits will move to including src.opts.mk instead of bsd.own.mk when
all that's needed is one of the MK_FOO options from src.opts.mk.
Future options should be placed here, unless they directly affect a
bsd.*.mk file, in which case they should be placed in bsd.opts.mk.

This is derived from the mps(4) driver, but it supports only the 12Gb
IT and IR hardware including the SAS 3004, SAS 3008 and SAS 3108.
Some notes about this driver:
o The 12Gb hardware can do "FastPath" I/O, and that capability is included in
this driver.
o WarpDrive functionality has been removed, since it isn't supported in
the 12Gb driver interface.
o The Scatter/Gather list handling code is significantly different between
the 6Gb and 12Gb hardware. The 12Gb boards support IEEE Scatter/Gather
lists.
Thanks to LSI for developing and testing this driver for FreeBSD.

lindev(4) was only used to provide /dev/full which is now a standard feature of
FreeBSD. /dev/full was never linux-specific and provides a generally useful
feature.
Document this in UPDATING and bump __FreeBSD_version. This will be documented
in the PH shortly.
