Is this patch adding CRC to the stats? If so that is wrong, stats should not
have the CRC.
A recent clarification from Andrew:
https://urldefense.proofpoint.com/v2/url?u=https-3A__patches.dpdk.org_patch_86975_&d=DwIDaQ&c=nKjWec2b6R0mOyPaz7xtfQ&r=M6lEONY3jVnAkBjt0yC6oAsT7Jn2HI7LhNHCQYlnx1Q&m=iYhQSv2FUrmxLNQcxo6cAiLpoeqeTx1mQKadLot0jh0&s=lYaS0RY6n4QOlhzd3Z9PTxtR42lbqxPt1Pm1uODpWJg&e=
[L.H.] okay, so based on this new clarification, this patch should not be
merged to both next and stable branches.
thanks
sure, I can drop it in next-net.
