The qlogicfc driver is based on the chris loveland work.
You can find outdated information here :

the qlogic driver is certainly based on this one too (look at the code, the
drivers differs not so much).
If you don't need IP support then keep using the qlogic driver which is far
better. I'm pretty sure that they have a working IP enhanced version but
for an unknow reason this one is not released. And without the IP-enhanced
firmware we can do nothing.
I've unsuccessfully tried to get information from qlogic and others a few
weeks ago.
IMHO the qlogicfc driver should be removed from the kernel tree and perhaps
replaced by the last qlogic one. We then lost the IP support but this is a
broken support.
The qlogicfc driver blocks the kernel each time a FC event occured and is
know to failed under heavy load (not so heavy, under load IMHO).
