[PATCH v2 3/9] app/testpmd: rework ieee1588 engine fwd configuration

[David Marchand]

This fwd engine currently ignores the forwarding configuration.
Force it explicitly when initialising the stream.
The code is then more consistent with other fwd engines (i.e. receiving
on fs->rx_port, transmitting on fs->tx_port).
