Implement (slightly) delayed entry into ELP. This will cure several
problems:
- It works around a firmware race condition if ELP is entered too fast
after commands (resulting in ELP timeout -traces)
- It will reduce the number of sleep-wake cycles between already
scheduled events such as interrupts and tx, hence improving
performance (less delay in switching between RX and TX)
