Hi Jiawen,

I put some comments on some patches, can you please send a new version with updates?

And I want to note that it is specially hard to review this PMD because it is 
clone of complete and complex ixgbe driver.
So most of the code is already ready, we are tying to structure it logically for 
upstreaming it but it is not possible to review the details of this much feature 
in this short time.

For those feature we are relying on the Wangxun to test all these features, and 
to confirm this, can it be possible for Wangxun to send some test results for 
this release?

Similar to those reports:
https://patches.dpdk.org/patch/84436/
https://patches.dpdk.org/patch/84500/
https://patches.dpdk.org/patch/84517/


Also quick test results for the -rc2 & -rc3 can be very helpful, if you can 
provide, like:

Thanks,
ferruh

Hi Ferruh,

Should I provide test results of PF part applied to the main repo, and VF part with
some modifications? I mean, the latest version that I format the patches.

Those reports show the NICs supported platforms. All features in dts report don't
to be needed, do they?

Hi Jiawen,

Sorry for the delay, I wasn't sure how to put this, there is no official defined 
process around it for now.

Testing reports can help on both:
1) A release with a new PMD can put some proof that new PMD is working as expected.
2) Gives some confidence for new patches to be merged.

This is to cover the case 1) above, as you said this is to document the 
platform/NIC tested for that release.

And this is for 2) above, it can have more details on the features tested, so it 
gives confidence and gives chance to detect and fix defect for the release.
