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.

Dr
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.

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
