This is another root level command for PMD specific feature, can this be
under "port" or "set" command?

Why not use existing defined hash functions but use custom one, is there
a missing one in ethdev?

I guess this will prevent auto completion.

These should not be defined by application I believe.

How user knows which values to fill the pctype_list?
More importantly, if this is an API call instead of user defined values,
how application should know which values to use? I am trying to say
pctype values defined in i40e driver somehow needs to public to be used.
