### Summary This PR is a follow-up of https://github.com/apache/nuttx/issues/15856 and the mailing list proposal "Proposal: Common IOCTL API for RF Modulation Technologies" Currently, the IOCTL API for character-driven RF devices lacks a common interface across different modulation technologies, such as LoRa, FSK, and OOK. As a result, driver-specific IOCTL commands are created even when they could be shared across multiple radios. This fragmentation makes application portability more difficult to maintain. This PR will add a common API that can be shared across all new drivers. Such as - LoRa - FSK - OOK / ASK - read() return struct ### Impact This change does not impact existing drivers by design. - Legacy drivers remain unchanged but can be ported if desired. - Experimental drivers can be freely adapted. - New drivers must use the common API whenever possible. The API covers the most common RF features. If additional functionality is required, new IOCTL commands can be introduced without breaking compatibility. Documentation updates will follow after the initial approval of this commit. Relevant to previous discussions: This update is no more a breaking change. No existing IOCTL commands have been replaced or removed. ### Testing This update is designed to be non-disruptive to existing drivers. However, some IOCTL command offsets have been adjusted. - Tested on: SX126x driver - Verification: The SX126x driver was tested using its driver-specific (non-common API) commands and continues to function as expected. - Next Steps: Since no drivers currently implement this API, further testing will occur during the porting process. -- This is an automated message from the Apache Git Service.
