    15  // Package eppolicymap represents the map from an endpoint ID to its
    16  // policy map. This map is of type BPF_MAP_TYPES_HASH_OF_MAPS where
    17  // as noted above the key is the endpoint ID. It is used to lookup
    18  // the policy from the socket context where unlike in the L2/L3 context,
    19  // where the program has a direct lookup of the policy because each
    20  // program is attached to an endpoint, socket programs run on all sockets
    21  // regardless of endpoint.
