Number of NCFs received from a source transport with reason code "ignored"
(LBT-RM, LBT-RU)

- n (Int32)
- Statistics set index

Number of NCFs received from a source with the reason
code set to "ignored".

If a source transport receives a NAK for a datagram that it has recently
retransmitted, it sends an "NCF ignored" and does not retransmit. How
recently" is determined by the configuration option for ignore interval.
If this count is high, a
receiver transport may be having trouble receiving retransmissions, or the
ignore interval may be set too long.
This method returns a value from the nth set of statistics
encapsulated within this object.
