In mlx5 HW, encapsulation is offloaded by the steering rule having index into an encapsulation table containing the entire set of headers to be added by the HW. The driver sets these headers in a buffer when we are offloading the action. The code maintains mlx5_encap_entry for each encap header it has encountered when attempted to offload TC tunnel set action. This entry maintains a linked list of all the flows sharing the same encap header, when the last flow is removed from the list the encap entry is removed. The actual encap_header is allocated by the driver in the hardware only if we have layer two neighbour info when the encap entry is created. While the flow is in the driver, the driver holds a reference on the neighbour. When a new flow with encap action is inserted, the code first checks if the required encap entry exists according to the tunnel set parameters. If it does the encap is shared, otherwise a new mlx5_encap_entry is created. TC action parsing implementation in the driver assumes that tunnel set action is provided in the same order set by the user, e.g before the mirred_redirect action.
