Thanks for the information. Sorry that we missed the patch. It was not done
out of specific reason.
As you have commented, it is a very large patch with alot of changes. We
wanted to submit
the patch to make sure the fundamental structure of the driver align with
the kernel. Once that
is in place, additional patch will be easier. Fushen will make sure this
change is in place on
the next submission.
