There is some inconsistency at least in the specification (I assume that
the implementation works).  /dev/net nodes are not observability nodes,
but full-fledged DLPI link nodes.  /dev/ipnet nodes are IP observability
nodes.  The new materials state:

+    using the /dev/net/ facility implemented for "Clearview: IP
+    Observability Devices" (PSARC 2006/475).  These nodes will be
+    named by the bridge name plus a trailing "0".

/dev/net nodes were added by 2006/499, and /dev/ipnet nodes by 2006/475.
The inconsistency should be fixed in the spec.
