This adds a new forwarding mode to testpmd, whereby it will forward packets, but on a transmit failure, it will wait a small amount of time before retrying the transmit again. This mode can be useful in some cases to set a zero-packet loss rate at the cost of overall throughput, especially in cases where TX ring size/buffering is constrained, such as with virtio.
