[dpdk-dev] [PATCH v2] app/testpmd: fix testpmd doesn't show RSS hash offload

[Jie Wang]

This patch reapply Rx/Tx offloads configuration for all ports
after the program configuring the device port. When the program
configures the ports, the default Rx/Tx offloads are modified in
dev->data->dev_conf.

So it is need to reapply Rx/Tx offloads configuration after
dev_configure.

v2: copy "rx/txmode.offloads", instead of copying the entire struct 
"dev->data->dev_conf.rx/txmode".
