+ * - Reply (0x08): This flow is in the reply direction, ie it did not

+ * - Invalid (0x10): This flow could not be associated with a connection.
+ * This could be set for a variety of reasons,
+ * including (but not limited to):
+ * - L3/L4 protocol handler is not loaded/unavailable.
+ * - L3/L4 protocol handler determines that the packet
+ * is malformed or invalid for the current FSM stage.
+ * - Packets are unexpected length for protocol.
+ * - Tracked (0x20): Connection tracking has occurred.
+ *
+ * The "Tracked" bit corresponds to the packet_state as described in the
+ * description of NXAST_CT action. The remaining bits correspond to
+ * connection state. The "New" bit implies that the connection state
+ * is uncommitted, while "Established" implies that it has previously been
+ * committed.

+ * of precedence below:

+ * - If "Tracked" is unset, no other bits may be set.
+ * - If "Tracked" is set, one or more other bits may be set.
+ * - If "Invalid" is set, only the "Tracked" bit is also set.
+ * - The "New" and "Established" bits are mutually exclusive.
+ * - The "New" and "Reply" bits are mutually exclusive.
+ * - The "Related" bit may be set in conjunction with any other bits.
+ * Connections that are identified as "Related" are separate
