Not directly.

I'm sorting through some of the Domain Validation code I got from
someboy at LSI-Logic. This current checkin is in support of that.

There's a possibility that some of the issues that have been seen (not
necessarily yours) are related to weaknesses in MPT firmware when Domain
Validation is *not* performed.

For example, if I connect an Ultra2 disk to an Ultra320 and have things
all negotiate correctly, and then power cycle the Ultra2 disk, the ARQ
data (auto request sense) for the subsequent check condition appears to
be mangled (I can't decide whether it was shifted by a byte or endian
fouled up). Nobody else has ever reported this, so I'm assuming it's due
to me not doing DV. Oh well.
