Hi.
Consider the following situation:
An application does
rte_event_eth_tx_adapter_enqueue()
and due to back-pressure or some other reason not all events/packets
could be enqueued, and a count lower than the nb_events input parameter
is returned.
The API says that "/../ the remaining events at the end of ev[] are not
consumed and the caller has to take care of them /../".
May an event device rearrange the ev array so that any enqueue failures
are put last in the ev array?
In other words: does the "at the end of ev[]" mean "at the end of ev[]
as the call has completed", or is the event array supposed to be
untouched, and thus the same events are at the end both before and after
the call.
The ev array pointer is not const, so from that perspective it may be
modified.
This situation may occur for example the bonding driver is used under
the hood. The bonding driver does this kind of rearrangements on the
ethdev level.
Thanks,
Mattias
