  Move fastpath inline function pointers from rte_cryptodev into a
separate structure accessed via a flat array.
The intension is to make rte_cryptodev and related structures private
to avoid future API/ABI breakages.

I think it has to be uintptr_t reserved[3];
2 function pointers + 3 data pointers +3 reserved pointers.
Otherwise it will occupy extra 64B line.

Yep, I missed decrementing it. Thanks. Will update in v4.
Please review others also and ack if no comments.
We need to close all the patches(including the control path)
by tomorrow EOD.

Ok.

I looked through other patches in this set.
All looks good to me.
With the nit above fixed:

Apart from the scheduler PMD changes required mentioned by Ciara,
re-acking this patch as all doubts are cleared on our end.
