The behavior you describe is correct - when the rebase argument is used,
the patch should be applied to HEAD of the branch specified by the rebase
arg.

However, I do believe there is a discrepancy in our labs behavior when it
comes to retests which are submitted without the rebase argument. In this
case, UNH lab, AWS, and GitHub are running retests on the original patch
artifacts without re-applying to the current HEAD at the time of the
retest. On the other hand, I believe Loongson does re-apply to HEAD even
when the rebase argument is not specified. I think in an ideal world our
behavior would be uniform across the labs. What that would require in this
case is either:

1. Loongson changes to retesting without re-apply on HEAD when no rebase
argument is given (unclear how much work this is)
OR
2. The other labs change their behavior to just re-apply on HEAD for every
retest, regardless of the rebase argument situation (probably not a lot of
implementation effort, but does reduce user flexibility a little).

Sounds like a good topic to discuss at an upcoming CI meeting. :)

I will send the dpdk-web patch noting that you have added rebase coverage.
Thanks Min Zhou.
