examples/l2fwd/main.c and examples/ethtool/ethtool-app/main.c are
probably the easier examples to follow. In terms of function calls, it
is pretty much:
rte_eal_init(..);
for (each port) {
rte_pktmbuf_pool_create(..);
rte_eth_dev_configure(..);
rte_eth_dev_rx_queue_setup(..);
rte_eth_dev_tx_queue_setup(..);
rte_eth_dev_start(..);
}
while(1) {
rte_eth_rx_burst(..); /* incoming frames */
rte_eth_tx_burst(..); /* outgoing frames */
}
Bear in mind that DPDK deals with MAC frames rather than higher level IP
packets, which may be an issue if you intend to use TCP/IP based
application protocols.
