run: add nic driver performance test

Browse Source 
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.
