Can you please elaborate on the standard interfaces you are referring to ?

Also as Roland mentioned in the other thread, echo-ing the parameters
to sysfs files
is a pretty straightforward way to configure the interfaces. Users
can setup configuration files to configure QLogic VNIC interfaces
specifying the name of the interface, various parameters of the
QLogic EVIC gateway target they want to use  and a simple user level
script parses the configuration file and echoes the parameters to the driver.
