722 | * @OVS_ACTION_ATTR_PUSH_MPLS: Push a new MPLS label stack entry onto the |
723 | * top of the packets MPLS label stack. Set the ethertype of the | |
724 | * encapsulating frame to either %ETH_P_MPLS_UC or %ETH_P_MPLS_MC to | |
725 | * indicate the new packet contents. | |
726 | * @OVS_ACTION_ATTR_POP_MPLS: Pop an MPLS label stack entry off of the | |
727 | * packet's MPLS label stack. Set the encapsulating frame's ethertype to | |
728 | * indicate the new packet contents. This could potentially still be | |
729 | * %ETH_P_MPLS if the resulting MPLS label stack is not empty. If there | |
730 | * is no MPLS label stack, as determined by ethertype, no action is taken. | |
7f8a436e JS |
731 | * @OVS_ACTION_ATTR_CT: Track the connection. Populate the conntrack-related |
732 | * entries in the flow key. | |
