The following patch series adds snic driver for Cisco SCSI HBA
Cisco has developed a new PCI HBA interface called sNIC, which stands for
SCSI NIC. This is a new storage feature supported on specialized network
adapter. The new PCI function provides a uniform host interface and abstracts

Hi James,
We had some performance problems with RAID systems connected to LPe12k.
AFAICS, the reason is a small bug in lpfc.ko, causing the IO-size to
be smaller than expected.
The patch below fixes it for us.
Please CC me, I'm not on the list.
Best regards

That's good to know. We have a fair amount of existing strings that are
split, so I don't want to retrofit those. But, on future submits, we'll
keep the string on a single line.

Bodo,
This is a valid fix. Thank you.
I assume you were changing the driver module parameter to up the SG
count ? without the fix we would have been capped at 64 sges.

Yes, we normally use 128, as this is the value best suited
for our RAID systems. After upgrading the software we saw
a clear performance reduction that was caused by the bug.
