Seth, I'm not sure why this message typed out strangely. I'll attempt to
fix that.
However the issue at had is, device "p1p1" is not a type of interface that
is recognized by tcpreplay. What type of hardware/software is it? If it
were an Ethernet device driven by the ixgbe driver, I would expect the
interface to be "ethX". Are there any "ethX" devices available that you
can use for your test? Finally, is this on a real or virtual machine?
Fred.
