Getting netmap to co-exist with user-space processes that use sockets

[VO Ipfix]

Hello there, I would like to use netmap with pptk (emulated driver) to
generate send traffic from an interface, but still allow rx/tx to get to
the the kernel so that other user-space networking processes function as
normal. Currently, if I open an interface eg netmap:eth0, other user space
processes are unable to perform any networking via sockets. How could I go
about solving this?

Thanks,
Victor
