Hi,

Adding support for IPsec events in rte_eth_event framework. In inline
IPsec offload, the per packet protocol defined variables, like ESN,
would be managed by PMD. In such cases, PMD would need IPsec events
to notify application about various conditions like, ESN overflow.

No comment about IPsec handling.
The documentation could try to better link things together, see below:
/**
+ * Subtypes for IPsec offload events raised by eth device.
+ */
+enum rte_eth_event_ipsec_subtype {
+ RTE_ETH_EVENT_IPSEC_UNKNOWN = 0,
+ /** Unknown event type */
+ RTE_ETH_EVENT_IPSEC_ESN_OVERFLOW,
+ /** Sequence number overflow in security offload */
+ RTE_ETH_EVENT_IPSEC_SA_TIME_EXPIRY,
+ /** Soft time expiry of SA */
+ RTE_ETH_EVENT_IPSEC_SA_BYTE_EXPIRY,
+ /** Soft byte expiry of SA */
+ RTE_ETH_EVENT_IPSEC_MAX
+ /** Max value of this enum */
+};
+
+/**
+ * Descriptor for IPsec event. Used by eth dev to send extra information of the
+ * event.

You could link it to the event type RTE_ETH_EVENT_IPSEC in this doxygen comment.
+struct rte_eth_event_ipsec_desc {
+ enum rte_eth_event_ipsec_subtype stype;
stype is not easy to read & understand. What about subtype?
+ /** Type of IPsec event */
You could add the prefix of the events in this comment: RTE_ETH_EVENT_IPSEC_*
+ uint64_t md;
What about metadata?
+ /** Event specific metadata */
Could you describe what is the metadata, depending on each sub-type?
