mfi driver update

[Ireneusz Pluta]

Hello,

I run a
     Product Name: LSI MegaRAID SAS 9280-16i4e
     Firmware: 12.13.0-0154

on the
     8.2-RELEASE FreeBSD 8.2-RELEASE #0: Thu Feb 17 02:41:51 UTC 2011

It may be the case that this box suffers from what is described here 
http://lists.freebsd.org/pipermail/freebsd-scsi/2011-March/004839.html, Generally my, not so 
frequent problem is getting stuck with COMMAND 0x... TIMEOUT AFTER sss SECONDS.

What I understand from there is that there was the mfi driver problem and it got resolved.

Could I just take the newwest /usr/src/sys/dev/mfi/* files back to this box and recompile the driver?
Or I get into system incompatibilities problems between 8.x and 10.x, eventually and I need some 
earlier version? Which?

Thanks
Irek.
