You've fixed one part of the issues I described, but I think you've left
open the possibility of dangling pointers when one card in a multi NIC
system fails to come up. Again, I need to track down the code to see if
I'm all wet or not.

I'd rather not have to undo the breakage when I fix it to my comfort --
best to get it right the first time if it is possible, and it is in this
instance. I'm not just worried about typhoon, I'm worried about the core
code and the other drivers you've converted. A brief skim over your tg3
and acenic patches suggests you took to heart the need to keep the
firmware around while the device is up, but the basic locking issues in
the core code suggest there are more lessons to be absorbed.

There's no way to get experience except by doing, and I applaud your
efforts to learn the code, but please drop the typhoon part and
concentrate on getting the core right. I've already committed to fixing
typhoon once you do.

Dave
