Ok, well there aren't too many folks using an QLA2100 in a fabric
topology, if there were, they wouldn't have gotten very far in the
driver load sequence.  I've been able to scrape-up a QLA2100, 1Gig
switch, and an JBOD.  Upon loading the 8.00.00b12k driver, the
firmware successfully logs into the switch, the driver receives a
LOOP_UP event, but, the kernel panics due to NULL pointer dereference
while trying to perform an RFT_ID  -- the attached patch against
current scsi-misc-2.6 fixes that problem.
