- /* Freezing complicates resubmit. There are two cases:
- *
- * - If mpls_pop has been executed, then the flow table lookup
- * as part of resubmit might depend on fields that can only
- * be obtained via recirculation, so the resubmit itself
- * triggers recirculation and we need to make sure that the
- * resubmit is executed again after recirculation.
- * Therefore, in this case we trigger recirculation and let
- * the code following this "switch" append the resubmit to
- * the post-recirculation actions.
- *
- * - Otherwise, some action in the flow entry found by resubmit
- * might trigger freezing. If that happens, then we do not
- * want to execute the resubmit again during thawing, so we
- * want to skip back to the head of the loop to avoid that,
- * only adding any actions that follow the resubmit to the
- * frozen actions.
