TODO (331B)
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.
