+notes:
+    - Cisco NX-OS creates the default VRF by itself. Therefore,
+      you're not allowed to use default as I(vrf) name in this module.
+    - I(vrf) name must be shorter than 32 chars.
+    - VRF names are not case sensible in NX-OS. Anyway, the name is stored
+      just like it's inserted by the user and it'll not be changed again
+      unless the VRF is removed and re-created. i.e. I(vrf=NTC) will create
+      a VRF named NTC, but running it again with I(vrf=ntc) will not cause
+      a configuration change.
