Detailed Description

kernel/user space shared circular buffer

this buffer is non-blocking for single-consumer/single-producer configurations; multiple producer write interleaved while obtaining shadow.tx; if shadow.tx==tx the producer is allowed to write into the buffer after advancing shadow.tx to the final tx position; once tx reaches shadow.tx the write is terminated and the producer can start a write cycle. multiple consumer each hold there own rx and read between rx and cycle.tx.
