There are a few other variant QLA2100s... the 'F' versions are fibreoptic.
There are copper versions. There are also clone (and cheaper) cards
available from Antares (http://www.antares.com) and Performance Technology
(http://www.pt.com).

Well, I'm the author of these drivers. I find them pretty good, but with
the proviso that:

a) Private loop only (working on fabric support now)

b) I don't handle loop id's shifting around. In two years of fooling
around with this, I've not really seen this happen.

Beyond that, they seem to work pretty well. But I've not had a very large
set of hardware to play with. I'd be very grateful for any feedback you
could provide.

Future plans:

	Fabrc and shifting port database support
	QLA2200 Support
	Target mode (within the next couple of months)
	Better Ultra2 support (the 1280)
