should we add, object like dev_id, vchan_id etc. Upto you.
IMO, We should tell about "silent" mode here and it is the implication
on rte_dmadev_completed_*
as "silent" changes above scheme in the completion side.

Without getting, capabilities application can not set zero. I would
suggest rewording
something like.
@note If some fields can not be supported by the hardware/driver, then
the driver ignores those
fields. Please check driver-specific documentation for limitations and
capablites.
