I'm not an expert of VMDq. Please help reviewing this doc addition. [..] > +/** > + * A structure used to configure the VMDQ feature of an Ethernet port when > + * not combined with the DCB feature. > + * > + * Using this feature, packets are routed to a pool of queues. By default, > the > + * pool selection is based on the MAC address, the vlan id in the vlan tag as > + * specified in the pool_map array. > + * Passing the ETH_VMDQ_ACCEPT_UNTAGGED in the rx_mode field allows pool > + * selection using only the MAC address. MAC address to pool mapping is done > + * using the rte_eth_dev_mac_addr_add function, with the pool parameter > + * corresponding to the pool id. > + * > + * Queue selection within the selected pool will be done using RSS when > + * it is enabled or revert to the first queue of the pool if not. > + * > + * A default pool may be used, if desired, to route all traffic which > + * does not match the vlan filter rules or any pool MAC address. > + */ > struct rte_eth_vmdq_rx_conf {
