Yes you have the OFED/kernel.org driver.

For this card do pull and load your drivers from the QLogic support
download area!  For this card the latest and greatest will be
on the QLogic site.  Also, pickup the documentation at the same time.....

The driver is built from source on the system for the active kernel.

And yes recall the OFED/kernel.org driver is missing the nonstop
recovery code for parity errors that have been observed on this card.
The kernel.org driver for this card detects the error and stops rather
than risk passing a data error.
