typedef int(* security_rx_inject_configure) (void *device, uint16_t port_id, bool enable)

Configure security device to inject packets to an ethdev port.

Parameters

device Crypto/eth device pointer
port_id Port identifier of the ethernet device to which packets need to be injected.
enable Flag to enable and disable connection between a security device and an ethdev port.

Returns

Perform security processing of packets and inject the processed packet to ethdev Rx.

Rx inject would behave similarly to ethdev loopback but with the additional security processing.

Parameters

device Crypto/eth device pointer
pkts The address of an array of nb_pkts pointers to rte_mbuf structures which contain the packets.
sess The address of an array of nb_pkts pointers to rte_security_session structures corresponding to each packet.
nb_pkts The maximum number of packets to process.

Returns

The number of packets successfully injected to ethdev Rx. The return value can be less than the value of the nb_pkts parameter when the PMD internal queues have been filled up.
