My understanding of Stephen's question is a bit different - Stephen please correct me if I'm wrong. By the comparison with FUSE he was thinking about providing a "kernel proxy" to userspace-based port/interface, which could be used not only by DPDK but by other too. The answer from me is: no I have not. For two reasons: - that would be Linux only - if we would create such proxy, we would probably end up with tap like driver in the end With regards Andrzej Ostruszka
