+ *
+ * @EFX_TC_EM_DIRECT: real HW entry in Outer Rule table; not a pseudo.
+ * Hardware index in &struct efx_tc_encap_match.fw_id is valid.
+ * @EFX_TC_EM_PSEUDO_MASK: registered by an encap match which includes a
+ * match on an optional field (currently only ip_tos), to prevent an
+ * overlapping encap match _without_ optional fields.
+ * The pseudo encap match may be referenced again by an encap match
+ * with a different ip_tos value, but all ip_tos_mask must match the
+ * first (stored in our child_ip_tos_mask).
