To let you (+ others know), we've been using this code on our systems
now for a while (7.x/i386,amd64), and all things point to a good solid
release that fixes the bugs we've come across with the current
drivers.

I will point out that we're a fairly generic FC/SAN configuration
though (HP to EVA - QMH2462 at 4Gb), so haven't had a need to test the
new features.

Excellent work, and hope to see it part of the distribution soon!

R.
