You know, this is probably slightly OTm, but I've been getting closer
and closer to what I consider 'happy' for my QLogic megadriver under
Linux- I have just a tad more to deal with in local loop failures (I
spent far too much time working on fabric only)- but I've been happier
with it and need to close it up and move on.

I *do* plan to finish IP support eventually.

I certainly would like to get more feedback about it.

Feel free to pick up-

It's certainly got the latest f/w in it which you can try and use with
qlogicfc.
