quic.SessionOptions.maxDatagramSendAttempts

The maximum number of SendPendingData cycles a datagram can survive without being sent before it is abandoned. When a datagram cannot be sent due to congestion control or packet size constraints, it remains in the queue and the attempt counter increments. Once the limit is reached, the datagram is dropped and reported as 'abandoned' via the ondatagramstatus callback. Valid range: 1 to 255.
