Maybe I am missing something here. For e.g. if the lowest timeout is 20 ticks, would you want 10 or 40 ? Currently, its set to 40.

Yes, it takes lock before calling rxa_sa_add. For internal_port implementation, I don't see any lock being taken. Besides, since its adapter related, it would be more relevant in adapter create than in queue add.

In current code, same condition check (queue_conf->rx_queue_flags & RTE_EVENT_ETH_RX_ADAPTER_QUEUE_EVENT_VECTOR ) is done twice next to each other, which could be avoided.
