please help backporting some patches to stable release 20.11.10

[Luca Boccassi]

At least for 22.11 it doesn't apply cleanly, context has changed quite

In the absence of that new feature being backported, I assumed there was no need to backport the fix, since others had not previously reported it. Since it seems that was a mistake, we should indeed look to backport the patch in question.

It did not patch cleanly because https://polaris-git.cisco.com/iosxe-dpt/cisco_dpdk/commit/4f8259df563a2f754cd99fa6191c9482ce2b2201 was not backported either.
