sas 5/i and mpt: hw.mpt.enable_sata_wc=1

[Peter Schuller]

Hello,

As per:

   http://lists.freebsd.org/pipermail/freebsd-stable/2007-July/036266.html

The hw.mpt.enable_sata_wc sysctl will enable write caching on SATA drives with 
the mpt driver. My question is, will explicit requests to flush the cache, 
such as those made by ZFS, still propagate to the drives?
