This patchset is to do some performance optimizations for hns3.

Huisong Li (5):
  net/hns3: fix incorrect index to look up table in NEON Rx
  net/hns3: fix the order of NEON Rx code
  net/hns3: optimize free mbuf code for SVE Tx
  net/hns3: optimize the rearm mbuf function for SVE Rx
  net/hns3: optimize SVE Rx performance

Hi Dongdong, Huisong,

Release is around a week away, OK to get critical fixes, but I can see
there are some optimizations as well.

Is this set for current release or next release?

If possible, we want this patchset can be applied for current release.

Thanks,

I can see there is a good performance increase, this makes harder to
defer but I am feeling this level of change is risky and you won't have
time to test and fix any issue.

Let me get first patch, as it is a fix. I can merge remaining patches
early in next release cycle.
@Thomas, what do you think?
