1 * currently the code introduces new IOCTLs. I'm afraid this is a bad idea.
2 -> Replace this with another interface, hints are welcome!
3 * Some missing data (marked with ###) needs to be added in the documentation
4 * Change (struct pi433_tx_cfg)->bit_rate to be a u32 so that we can support
5 bit rates up to 300kbps per the spec.
