01. Does the feature break API/ABI?

 NO.

02. Does the feature break backwards compatibility?

 NO.

03. Is it for the latest LTS release (to avoid LTS upgrade issues)?

Yes.

04. Is there a commitment from the proposer or affiliation to validate the feature and check for regressions in related functionality?

Passed internally, if needed, an official Test-by can be provided. 

05. Is there a track record of the proposer or affiliation validating stable releases?

Bugzilla ?

06. Is it obvious that the feature will not impact existing functionality?

Yes.

07. How intrusive is the code change?

 From LOC, yes, 1.9K seems to be BIG, but DPDK PMD related is 588, other is
 the share code in base (1320), which is tested and validated on other platform.

08. What is the scope of the code change?

PMD only.

09. Does it impact common components or vendor specific?

NO.

10. Is there a justifiable use case (a clear user need)?

Yes, for firmware updated. And we have the customer who wants to use the
VLAN feature on LTS 20.11.

11. Is there a community consensus about the backport?
