[dpdk-dev] [PATCH] app/testpmd: introduce QinQ and Rx offloads argument

[viveksharma at marvell.com]

From: Vivek Sharma <viveksharma at marvell.com>

Introduce boot time argument for configuring QinQ strip
offload and for configuring all rx offloads.Fix port info
display to distinguish between qinq strip and extend offloads.
