 53Description:
 54		The .../XXXXXXX.ipa/endpoint_id/ directory contains
 55		attributes that define IDs associated with IPA
 56		endpoints.  The "rx" or "tx" in an endpoint name is
 57		from the perspective of the AP.  An endpoint ID is a
 58		small unsigned integer.

 82Description:
 83		The .../XXXXXXX.ipa/endpoint_id/monitor_rx file contains
 84		the ID of the AP endpoint on which IPA "monitor" data is
 85		received.  The monitor endpoint supplies replicas of
 86		packets that enter the IPA hardware for processing.
 87		Each replicated packet is preceded by a fixed-size "ODL"
 88		header (see .../XXXXXXX.ipa/feature/monitor, above).
 89		Large packets are truncated, to reduce the bandwidth
 90		required to provide the monitor function.
