IGC Poll Mode Driver
|
|
======================
|
|
|
|
The IGC PMD (**librte_net_igc**) provides poll mode driver support for Foxville
|
|
I225 Series Network Adapters.
|
|
|
|
- For information about I225, please refer to: `Intel® Ethernet Controller I225 Series
|
|
<https://ark.intel.com/content/www/us/en/ark/products/series/184686/intel-ethernet-controller-i225-series.html>`_.
|
|
|
|
|
|
Driver compilation and testing
|
|
------------------------------
|
|
|
|
Refer to the document :ref:`compiling and testing a PMD for a NIC <pmd_build_and_test>`
|
|
for details.

Sample Application Notes
|
|
------------------------
|
|
|
|
Vlan filter
|
|
~~~~~~~~~~~
|
|
|
|
VLAN stripping off only works with inner vlan.
|
|
Only the outer VLAN TPID can be set to a vlan other than 0x8100.
|
|
|
|
If extend VLAN is enabled:
|
|
|
|
- The VLAN header in a packet that carries a single VLAN header is treated as the external VLAN.
|
|
|
|
- Foxville expects that any transmitted packet to have at least the external VLAN added by the
|
|
software. For those packets where an external VLAN is not present, any offload that relates to
|
|
inner fields to the EtherType might not be provided.
|
|
|
|
- If VLAN TX-OFFLOAD is enabled and the packet does not contain an external VLAN, the packet is
|
|
dropped, and if configured, the queue from which the packet was sent is disabled.
|
|
|
|
To start ``testpmd``, add vlan 10 to port, set vlan stripping off on, set extend on, set TPID of
|
|
outer VLAN to 0x9100:
|
|
|
|
.. code-block:: console
|
|
|
|
./app/dpdk-testpmd -l 4-8 -- -i
|
|
...
|
|
|
|
testpmd> vlan set filter on 0
|
|
testpmd> rx_vlan add 10 0
|
|
testpmd> vlan set strip off 0
|
|
testpmd> vlan set extend on 0
|
|
testpmd> vlan set outer tpid 0x9100 0
|
|
|
|
|
|
Flow Director
|
|
~~~~~~~~~~~~~
|
|
|
|
The Flow Director works in receive mode to identify specific flows or sets of flows and route
|
|
them to specific queues.
|
|
|
|
The Flow Director filters includes the following types:
|
|
|
|
- ether-type filter
|
|
- 2-tuple filter(destination L4 protocol and destination L4 port)
|
|
- TCP SYN filter
|
|
- RSS filter
|
|
|
|
Start ``testpmd``:
|
|
|
|
.. code-block:: console
|
|
|
|
./dpdk-testpmd -l 4-8 -- i --rxq=4 --txq=4 --pkt-filter-mode=perfect --disable-rss
|
|
|
|
Add a rule to direct packet whose ``ether-type=0x801`` to queue 1:
|
|
|
|
.. code-block:: console
|
|
|
|
testpmd> flow create 0 ingress pattern eth type is 0x801 / end actions queue index 1 / end
|
|
|
|
Add a rule to direct packet whose ``ip-protocol=0x6(TCP), tcp_port=0x80`` to queue 1:
|
|
|
|
.. code-block:: console
|
|
|
|
testpmd> flow create 0 ingress pattern eth / ipv4 proto is 6 / tcp dst is 0x80 / end actions queue index 1 / end
|
|
|
|
Add a rule to direct packet whose ``ip-protocol=0x6(TCP), SYN flag is set`` to queue 1:
|
|
|
|
.. code-block:: console
|
|
|
|
testpmd> flow validate 0 ingress pattern tcp flags spec 0x02 flags mask 0x02 / end actions queue index 1 / end
|
|
|
|
Add a rule to enable ipv4-udp RSS:
|
|
|
|
.. code-block:: console
|
|
|
|
testpmd> flow create 0 ingress pattern end actions rss types ipv4-udp end / end
