v6: - fix tx queue state check in rte_eth_rx_queue_setup - fix error message in testpmd.
v5: - fix first tx queue check in i40e. v4: - fix i40e rx/tx funciton conflict handle. - no need conflict check for first rx/tx queue at runtime setup. - fix missing offload paramter in testpmd cmdline. v3: - not overload deferred start. - rename deferred setup to runtime setup. - remove unecessary testpmd parameters (patch 2/4 of v2) - add offload support to testpmd queue setup command line - i40e fix: return fail when required rx/tx function conflict with exist setup. v2: - enhance comment in rte_ethdev.h According to exist implementation,rte_eth_[rx|tx]_queue_setup will always return fail if device is already started(rte_eth_dev_start). This can't satisfied the usage when application want to deferred setup part of the queues while keep traffic running on those queues already be setup. example: rte_eth_dev_config(nb_rxq = 2, nb_txq =2) rte_eth_rx_queue_setup(idx = 0 ...) rte_eth_rx_queue_setup(idx = 0 ...) rte_eth_dev_start(...) /* [rx|tx]_burst is ready to start on queue 0 */ rte_eth_rx_queue_setup(idx=1 ...) /* fail*/ Basically this is not a general hardware limitation, because for NIC like i40e, ixgbe, it is not necessary to stop the whole device before configure a fresh queue or reconfigure an exist queue with no traffic on it. The patch let etherdev driver expose the capability flag through rte_eth_dev_info_get when it support deferred queue configuraiton, then base on these flag, rte_eth_[rx|tx]_queue_setup could decide continue to setup the queue or just return fail when device already started.
