This attribute is replaced by new attributes rxCellDiscard and
rxFrameDiscard.
This attribute counts the number of cells or frames received from
the interface on this connection that have been discarded.
If the connection segments frames into cells, the counter indicates
the number of frames discarded. Connections which segment
frames into cells have a connectionPointType of
connectionEndPoint.
If the connection relays cells without adaptation, the counter
indicates the number of cells discarded. Connections which relay
cells without adaptation have a connectionPointType of
segmentEndPoint or connectingPoint.
AAL1 connections are an exception to this rule; although they have
a connectionPointType of connectionEndPoint, they do not do
adaptation at this point. Thus, in the AAL1 case, this attribute
counts discarded cells.
Discards are done due to congestion, non-conformance with UPC or
AAL reassembly problems.
The counter wraps to zero if it exceeds its maximum value of
(2**64)-1.
