run: add nic driver performance test
A run script which sends raw ethernet packets from the host machine to the target machine. Three tests are implemented: - The network_stat instrumented driver of usb_drv and net_drv are used to get the raw receive performance of the network driver. - A simple nic_session client is receiving from the un-instrumented network driver raw ethernet packets. - A bridge is added between driver and simple nic_session client.
