[dpdk-dev] [PATCH] 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.

So it is need to reapply Rx/Tx offloads configuration before
testpmd showing offloads.
