Hi ethdev maintainers, I am looking for the exact expectation from the PMD upon a call for rte_eth_dev_stop. The doc is a bit lacking[1].
Assuming stop should do the opposite of start[2], Does it mean after call to dev_stop the DPDK port should no longer receive traffic? What should be the link status after a call to dev_stop? From [2] it seems like a don't care since the link_status callback is not enabled. [1] /** * Stop an Ethernet device. The device can be restarted with a call to * rte_eth_dev_start() * * @param port_id * The port identifier of the Ethernet device. */ void rte_eth_dev_stop(uint16_t port_id); [2] /** * Start an Ethernet device. * * The device start step is the last one and consists of setting the configured * offload features and in starting the transmit and the receive units of the * device. * On success, all basic functions exported by the Ethernet API (link status, * receive/transmit, and so on) can be invoked. * * @param port_id * The port identifier of the Ethernet device. * @return * - 0: Success, Ethernet device started. * - <0: Error code of the driver device start function. */ int rte_eth_dev_start(uint16_t port_id);
