General comment on implementation approach:
IMO, we should avoid PMD details in common lib area.
example: file channel_commons.h has ifdef clutter referencing
i40e pmds all over.
Perhaps we should introduce opaque handle example void * or introduce pmd
specific callback/handle which points to PMD specific metadata in power library.
Example:
struct channel_packet {
void *pmd_specific_metadata;
}
Or someway via callback (I'm not sure at the moment)
so that we could hide PMD details in common area.
Thanks.
