The transceiver reset takes quite a while. It seems that also going into
sleep mode has the effect of stopping cw test mode and it's much faster.
This has only been tried on the AT86RF231. For AT86RF230, we therefore
still use the reset.
Performance improvement:
Measurement: atrf-path sweep time in GUI mode, averaging over 10 samples.

When some interrupt(s) happened but the one(s) wait_for_interrupt was
waiting for weren't among them, it printed the list of interrupts
even if they were all in "ignore". This made sequences like RX_START

According to the data sheet, it has to be enabled. The Software Model
doesn't mention it. Experiments show that it's indeed useless and just
adds noise.
