 These TAP interfaces can be used with Wireshark or tcpdump or Pktgen-DPDK
 along with being able to be used as a network connection to the DPDK
 application. The method enable one or more interfaces is to use the
-``--vdev=net_tap`` option on the DPDK application command line. Each
-``--vdev=net_tap`` option give will create an interface named dtap0, dtap1,

 Also the speed of the interface can be changed from 10G to whatever number
 needed, but the interface does not enforce that speed, for example::
 
-   --vdev=net_tap,iface=foo0,speed=25000
+   --vdev=net_tap0,iface=foo0,speed=25000
 
 After the DPDK application is started you can send and receive packets on the
 interface using the standard rx_burst/tx_burst APIs in DPDK. From the host
