wait PIFS after end-of-tx. If idle, call MacLowTransmissionListener::MissedAck.
if busy at end-of-tx+PIFS, wait end-of-rx
if Ack ok at end-of-rx, call MacLowTransmissionListener::GotAck.
if Ack not ok at end-of-rx, report call MacLowTransmissionListener::MissedAck at end-of-rx+SIFS.

This is really complicated but it is needed for proper HCCA support.

Parameters

size	size of next data to send after current packet is sent.

Add the transmission duration of the next data to the durationId of the outgoing packet and call MacLowTransmissionListener::StartNextFragment at the end of the current transmission + SIFS.
