I am about to try the rocket raid in IT mode because I am tired of fighting with lsi firmware. Very very stable when you get the right combo, 1000's of phantom checksum errors if not.

FreeBSD 10.3 :
# egrep ^mps0 /var/run/dmesg.boot
mps0: <Avago Technologies (LSI) SAS2008>
mps0: Firmware: 20.00.04.00, Driver: 20.00.00.00-fbsd

FreeBSD 11-RC1 :
# egrep ^mps0 /var/run/dmesg.boot
mps0: <Avago Technologies (LSI) SAS2008>
mps0: Firmware: 20.00.04.00, Driver: 21.01.00.00-fbsd

Strangely enough there is no P21 driver/firmware @Avago :

So I assume firmware P20 is the right one to use with FreeBSD 11.
Well it is : https://forums.freenas.org/index.php?threads/firmware-version-p21.45130/#post-304399

I did not test firmwares 20.00.05.00 / 20.00.06.00 / 20.00.07.00.
Did you ?
Unfortunately changelog for 20.00.05.00 is no more available online, so no idea what it does.
The 2 others are, 3 + 1 defects corrected, should be worth it at first glance.
