[dpdk-dev] [PATCH 3/5] app/testpmd: check not configuring port twice

[Thomas Monjalon <thomas@monjalon.net>]

It is possible to request probing of a device twice,
and possibly get new ports for this device.
However, the ports which were already probed and setup
must not be setup again. That's why it is checked whether
the port is already part of fwd_ports_ids array at the beginning
of the function setup_attached_port().
