The class we have today in mainline and that patch was for the 
iscsi_sfnet driver. The open-iscsi driver in James's iscsi tree has a 
updated class. It is geared twords open-iscsi's design and so it has 
some things that may not work so well for qla4xxx off the bat due to 
what could live in userspace for us and what you do in firmware and 
where the scsi_host is allocated etc.
