Thanks! Let's see if we get an ack.
Minor things for the future (in case a new version will be needed):
Subject should include the patch version. Also pls avoid
capital letters in the middle of the sentence. E.g.
[PATCH v3] vDPA/ifcvf: fix the calculation of queuepair

An extra " " here at the end.
It's also a good idea to add:
Fixes: 2ddae773c93b ("detect and use the onboard number")

A good thing to add here is a changelog.
In this case the patch is unchanged, so you would write:
changes in v2:
- updated commit log with more info, addressing comments by MST
- no code changes
add more versions to this as you are revising the patch.
