+Description:
+ Boolean attribute showing the status of the "NDP to
+ end" quirk. Defaults to 'N', except for devices
+ already known to need it enabled.
+
+ The "NDP to end" quirk makes the driver place the NDP
+ (the packet index table) after the payload. The NCM
+ specification does not mandate this, but some devices
+ are known to be more restrictive. Write 'Y' to this
+ attribute for temporary testing of a suspect device
+ failing to work with the default driver settings.
+
+ A device entry should be added to the driver if this
+ quirk is found to be required.
