Contributions summary:Ciro primarily contributed to the UHD (USRP™ Hardware Driver) repository by fixing bugs and adding new example code. Their work included defining and modifying the UHD API macro to resolve compilation errors when building static libraries on Windows and fixing rounding errors in DDC/DUC rate calculation. They also added a benchmark streamer example that tests different streaming code paths. Furthermore, the user added the traffic counter to null source sinks, which helps with performance analysis. They also added support for multi-channel and dual ethernet configurations to the benchmark streamer.
