+ <code>decay_min_rx</code> is used to set the <code>min_rx</code>,
+ when there is no obvious incoming data traffic at the interface.
+ It cannot be set less than the <code>min_rx</code>. The decay feature
+ is disabled by setting the <code>decay_min_rx</code> to 0. And the
+ feature is reset everytime itself or <code>min_rx</code> is
+ reconfigured.

+ <column name="bfd" key="forwarding_if_rx" type='{"type": "boolean"}'>
+ When <code>forwarding_if_rx</code> is true the interface will be
+ considered capable of packet I/O as long as there is packet
+ received at interface. This is important in that when link becomes
+ temporarily conjested, consecutive BFD control packets can be lost.
+ And the <code>forwarding_if_rx</code> can prevent link failover by
+ detecting non-control packets received at interface.
