Hi, I am trying to explore the possibility to build a network SPAN/TAP from net= map. Similar to the bridge sample, but all packet going through the bridge = also get copied to a SPAN port. How do I duplicate or clone an incoming pac= ket and send the original to bridge peer and the cloned one to the SPAN por= t? Is there an API like FreeBsd m_copypacket() for netmap? Would it work fo= r Linux as well? Thanks Ming
