This attribute counts the number of packets received from the
remote module that have been discarded. It is a vector indexed by
the emission priorities (ep0, ep1 and ep2) of the packets. The
highest emission priority is ep0. These counters wrap around to zero
when the maximum value is exceeded.
Two main reasons that cause this counter to increment are:
(1) the remote protocol is not compatible to the local protocol stack
and,
(2) the packet cannot be forwarded due to either a recent loss of
connectivity or due to congestion.
