Hi Li,

I am not clear with the dependency chain, can you please clarify,

1) Is this set depends to series-16301? Because it compiles fine after conflict 
resolved, I can see in your repo there is an order, but if there is no 
functional/logical dependency you can set this patch exactly on top of HEAD 
(removing the series-16301 in between), so the CI will be enabled.

2) According its cover letter series-16301 depends on mlx ASO patch, this makes 
all ethdev patches dependent to mlx5 set, I guess that is wrong, can you please 
confirm?

Above (1) is more important, since series-16301 not fully acked, it is blocking 
me to proceed.
