Hi Amiya,

Thanks for the patch.
Since your first patch was already merged into the main branch, this patch is considered a new patch (v1).
If you submit another revision, it should be labelled v2.

Since it's a new patch, it needs a new commit message. Something like:

net/iavf: fix VLAN strip disabling for v2 capability

Ensure the correct virtchnl op is called for disabling vlan stripping by checking if the device supports either v1 or v2 vlan capability and choosing the op accordingly.

You should include the below line in the commit message which indicates it is a fix for the first patch:
Fixes: 3bfad066f9b4 ("net/iavf: fix VLAN strip setting after enabling filter")

Thanks,
Ciara
