openvswitch: include datapath actions with sampled-packet upcall to userspace
If new optional attribute OVS_USERSPACE_ATTR_ACTIONS is added to an OVS_ACTION_ATTR_USERSPACE action, then include the datapath actions in the upcall. This Directly associates the sampled packet with the path it takes through the virtual switch. Path information currently includes mangling, encapsulation and decapsulation actions for tunneling protocols GRE, VXLAN, Geneve, MPLS and QinQ, but this extension requires no further changes to accommodate datapath actions that may be added in the future. Adding path information enhances visibility into complex virtual networks. Signed-off-by: Neil McKee <neil.mckee@inmon.com> Signed-off-by: David S. Miller <davem@davemloft.net>
