Summary

Beginning of test suite for RN2483 driver. At this point only check ioctl calls that handle the 'get' and 'set' commands of the radio parameters. Due to local issues in my build environment, I cannot find a way to actually run these tests, so I need someone else to run these tests while having the radio process running.

Impact

Update this section, where applicable, on how change affects users,
build process, hardware, documentation, security, compatibility, etc.

Testing

No testing done yet, will do once reviewed.

…ice. Implemented with the rn2483_radio_set_cmd function which uses an enum to represent each cmd and sends a radio set <message> to set the desired values of the corresponding cmd. void *data is the generic pointer which will be set to different data types, so appropriate pointer casting was used. All inputs to the radio_set_cmd function are presumed to have already been checked, which is why there are no checks in the function itself. A dummy file_read call is a temporary fix to get rid of an annoying bug where the 'sys get ver' value would be the first values in the read buffer after startup. Logging is used mostly for debugging at this point through syslog.
…te functions. Removed all enums related to rn2483_radio_set_cmd.
…nger than required in case we need to adda null terminating character.
…ed define for dummy read buffer length. Would like to get rid of dummy read eventually.
… recommended. I am also subtracting one to keep space for the null terminating character.
…t, set priv->config options after sending the radio command instead of before, and now check for the error return value from that radio command call before setting the config's parameters.
…ctl. I was not able to run them so someone else needs to run them to ensure functionality. Might be worth putting assert statements to prevent get commands being called when the set command failed.
