Returns • 0 if successful. • -EINVAL if context NULL or port_id is invalid. • -EBUSY if devices are not in stopped state. • -ENOTSUP if security device does not support injecting to ethdev port. See also rte_security_inb_pkt_rx_inject __rte_experimental uint16_t rte_security_inb_pkt_rx_inject (void * ctx, struct rte_mbuf ** pkts, void ** sess, uint16_t nb_pkts) Warning EXPERIMENTAL: this API may change, or be removed, without prior notice 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. In case of ethdev loopback, application would be submitting packets to ethdev Tx queues and would be received as is from ethdev Rx queues. With Rx inject, packets would be received after security processing from ethdev Rx queues. With inline protocol offload capable ethdevs, Rx injection can be used to handle packets which failed the regular security Rx path. This can be due to cases such as outer fragmentation, in which case applications can reassemble the fragments and then subsequently submit for inbound processing and Rx injection, so that packets are received as regular security processed packets. With lookaside protocol offload capable cryptodevs, Rx injection can be used to perform packet parsing after security processing. This would allow for re-classification after security protocol processing is done (ie, inner packet parsing). The ethdev queue on which the packet would be received would be based on rte_flow rules matching the packet after security processing. The security device which is injecting packets to ethdev Rx need to be configured using rte_security_rx_inject_configure with enable flag set to true before any packets are submitted. If hash.fdir.h field is set in mbuf, it would be treated as the value for MARK pattern for the subsequent rte_flow parsing. The packet would appear as if it is received from port field in mbuf. Since the packet would be received back from ethdev Rx queues, it is expected that application retains/adds L2 header with the mbuf field 'l2_len' reflecting the size of L2 header in the packet. Parameters ctx Security ctx 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 security sessions 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.
