Trying to kick-start this again...
I've updated the prior RFC with the comments from Seokmann,
SvenFujita, and Boaz. I would still like review on the
blk_xxx completion calls in the std and error paths.
I'm looking the driver changes to match it with latest updates in
the transport layer.
The driver with the changes should be available within a couple of
weeks.
Here is a change that I've made for transport layer while I'm testing
the feature.

With this change, I'm able to issue several ELS/CT services to the
qla2xxx module for those registered to the transport layer and have
rport associated with them.
And, below is the driver changes for just review purpose.
Do we have time table for this support to make it available in the
upstream?
I think it would be good to have the feature in 2.6.30 kernel, if
possible.
I will continue to work on and add rest of helper function in the
driver.
Thank you,
Seokmann
