False. Go to rev 1.1 of isp_pci.c && isp.c && asm_pci.h. F/W download
was conditional only there being a fwlen of non-zero.

You asked for a config option to turn off f/w downloads. Also, I started
trying, at one point, to pay attention to the f/w revisions in currently
running (i.e., loaded by SRM) f/w and not loading on top of that.

The latter turned out to be a lose because the version numbers vary
depending on what feature sets you have. It's also not clear where
Digital's f/w (which they probably do themselves) fits in.

It does a better job now of working with older and different f/w sets.
We're talking about two years of fooling around with this now since then,
and while I'm kinda stupid, I *do* learn from experience.
