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
