tx_pcap=/path/to/file.pcap
* rx_iface: Defines a reception stream based on a network interface name.
- The driver reads packets coming from the given interface using the Linux kernel driver for that interface.
+ The driver reads packets from the given interface using the Linux kernel driver for that interface.
+ The driver captures both the incoming and outgoing packets on that interface.
The value is an interface name.
rx_iface=eth0
+* rx_iface_in: Defines a reception stream based on a network interface name.
+ The driver reads packets from the given interface using the Linux kernel driver for that interface.
+ The driver captures only the incoming packets on that interface.
+ The value is an interface name.
+
+ rx_iface_in=eth0
+
* tx_iface: Defines a transmission stream based on a network interface name.
The driver sends packets to the given interface using the Linux kernel driver for that interface.
The value is an interface name.
iface=eth0
+Runtime Config Options
+^^^^^^^^^^^^^^^^^^^^^^
+
+- Use PCAP interface physical MAC
+
+ In case ``iface=`` configuration is set, user may want to use the selected interface's physical MAC
+ address. This can be done with a ``devarg`` ``phy_mac``, for example::
+
+ --vdev 'net_pcap0,iface=eth0,phy_mac=1'
+
Examples of Usage
^^^^^^^^^^^^^^^^^
$RTE_TARGET/app/testpmd -l 0-3 -n 4 \
--vdev 'net_pcap0,iface=eth0' --vdev='net_pcap1;iface=eth1'
+Enable 2 tx queues on a network interface:
+
+.. code-block:: console
+
+ $RTE_TARGET/app/testpmd -l 0-3 -n 4 \
+ --vdev 'net_pcap0,rx_iface=eth1,tx_iface=eth1,tx_iface=eth1' \
+ -- --txq 2
+
+Read only incoming packets from a network interface and write them back to the same network interface:
+
+.. code-block:: console
+
+ $RTE_TARGET/app/testpmd -l 0-3 -n 4 \
+ --vdev 'net_pcap0,rx_iface_in=eth1,tx_iface=eth1'
+
