Thanks for your reply.
I will check and try an older version of netmap.

Unfortunately, this seems to happen a lot with netmap. Their API has
no backward compatibility. I have asked them to be careful with this
in the past, but it appears that their new version no longer works
with anything older. Therefore, I either have to write a version of
tcpreplay for every version of netmap, or else I will have to fork
their code and hard wire to a specific version.
I'll try to come up with a solution. In the mean time, I have opened
the following issue https://github.com/appneta/tcpreplay/issues/195
The quick_tx issue is a known issue. Unfortunately it does not work on
every driver/NIC combination. I will see if the author has time to
look at this, otherwise I will try to get up to speed on it myself.
