After more check, I also find these one:
$ git grep "NET.*_PID\|NET.*_FD" include/uapi/linux/
include/uapi/linux/devlink.h:   DEVLINK_ATTR_NETNS_FD,                  /* u32 */
include/uapi/linux/devlink.h:   DEVLINK_ATTR_NETNS_PID,                 /* u32 */
include/uapi/linux/gtp.h:       GTPA_NET_NS_FD,
include/uapi/linux/if_link.h:   IFLA_NET_NS_PID,
include/uapi/linux/if_link.h:   IFLA_NET_NS_FD,
include/uapi/linux/net_namespace.h:     NETNSA_PID,
include/uapi/linux/net_namespace.h:     NETNSA_FD,
include/uapi/linux/nl80211.h:   NL80211_ATTR_NETNS_FD,
