Hi Akhil,

Thanks for looking at this.

The flags we have in mind are very PMD specific i.e. controlling 
specific hardware behavior so they will not be suitable to be added to 
the common flags.

Seeing that aux_flags are not that strongly defined and seeing that they 
are already potentially used for PMD specific values my reasoning was to 
formalize this possibility of usage

aux_flags are used here to potentially carry a value that is not covered 
in the common API aux_flags definitions:
