[dpdk-ci] Failures reported by Intel CI for series 10551

[Chen, Zhaoyan]

Hi all,

I have updated the info for this issue in bugzilla.


We have re-built the patchset. It was passed. The root cause is that patches in the  series are disorder by patchid. (patch 7/9 and patch 8/9). Usually, we apply patches by the order of patch id in a series. 

Why the issue is exposed this time?

Meet 2 conditions,
- the patches are disorder in the series
- the disordered patches are modified same file

Solution
- Change applying patch order by patch date, rather than patch id in patchwork.
But we don't know if patch date is unique and ordered for each patch in the series. 
We need patchwork document to confirm. So far, its good.


For Thomas' suggestion, "sending the series report only on the last patch of the series", currently, I find all reports iol-* are sent to the first patch in the series. Shall we align? and shall we get feedback from all maintainers or developers in the community?



Regards,
Zhaoyan Chen
