[v4,0/4] Support PPS(packet per second) on meter

  Currently meter algorithms only supports rate is bytes per second(BPS).
Add packet_mode flag in meter profile parameters data structure.
So that it can meter traffic by packet per second.

When packet_mode is 0, the profile rates and bucket sizes are
specified in bytes per second and bytes
when packet_mode is not 0, the profile rates and bucket sizes are
specified in packets and packets per second.

Add the necessary checks to the existing drivers implementing
the rte_mtr API to makes sure that profiles with
packet_mode set to TRUE are rejected.

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.

I will delete series-16301.
But it will merge conflict when series-16301 merged after it.

Please send both this patch, and series-16301 on top of latest head, this 
enables CI for both.

When merging them we can handle the conflict, based on which one merged first, 
or can ask you to rebase the second one but for this case it does not look too 
complex to resolve ourselves.

Got it and will sent it on V5 patch.
