I thought about that too, but it seems more drawbacks then pluses with that idea: 1. Right now it is possible to call rte_eth_rx_queue_setup(..., rx_conf=NULL, ...); In that case rte_eth_rx_queue_setup()will use default for that device rx_conf. If we'll move mempool into rxconf, will break that ability. 2. A bit unclear what mempool should be returned as default_rxconf by rte_eth_dev_info_get(). Should it be just NULL. 3. ABI breakage and we (and all customers) will need to modify each and every RX setup/configure code. For me it just seems like too much hassle, without any clear advanatage. > > > -#ifdef __cplusplus > > -} > > -#endif > > - > > /** > > * Set the list of multicast addresses to filter on an Ethernet device. > > * > > @@ -3882,4 +3952,9 @@ extern int rte_eth_timesync_read_rx_timestamp(uint8_t > > port_id, > > */ > > extern int rte_eth_timesync_read_tx_timestamp(uint8_t port_id, > > struct timespec *timestamp); > > + > > +#ifdef __cplusplus > > +} > > +#endif > > + > > #endif /* _RTE_ETHDEV_H_ */ > > Please send this change in a separate patch alone. Ok, will do. Konstantin
