A per port offloading feature should be enabled or disabled at same time in both rte_eth_dev_configure( ) and rte_eth_rx_queue_setup( )/rte_eth_tx_queue_setup( ). This patch check if a per port offloading flag has same configuration in rte_eth_dev_configure( ) and rte_eth_rx_queue_setup( )/rte_eth_tx_queue_setup( ). This patch can make such checking in a common way in rte_ethdev layer to avoid same checking in underlying PMD.
