7 The IGC PMD (librte_pmd_igc) provides poll mode driver support for Foxville
8 I225 Series Network Adapters.
10 - For information about I225, please refer to:

17 The following options can be modified in the ``config`` file.
18 Please note that enabling debugging options may affect system performance.
20 - ``CONFIG_RTE_LIBRTE_IGC_PMD`` (default ``y``)
22 Toggle compilation of the ``librte_pmd_igc`` driver.
24 - ``CONFIG_RTE_LIBRTE_IGC_DEBUG_*`` (default ``n``)
26 Toggle display of generic debugging messages.

45 Sample Application Notes
46 ------------------------
51 VLAN stripping off only works with inner vlan.
52 Only the outer VLAN TPID can be set to a vlan other than 0x8100.
54 If extend VLAN is enabled:
56 - The VLAN header in a packet that carries a single VLAN header is treated as the external VLAN.
58 - Foxville expects that any transmitted packet to have at least the external VLAN added by the
59 software. For those packets where an external VLAN is not present, any offload that relates to
60 inner fields to the EtherType might not be provided.
62 - If VLAN TX-OFFLOAD is enabled and the packet does not contain an external VLAN, the packet is
63 dropped, and if configured, the queue from which the packet was sent is disabled.
65 To start ``testpmd``, add vlan 10 to port, set vlan stripping off on, set extend on, set TPID of
68 .. code-block:: console
70 ./app/testpmd -l 4-8 -- -i
73 testpmd> vlan set filter on 0
74 testpmd> rx_vlan add 10 0
75 testpmd> vlan set strip off 0
76 testpmd> vlan set extend on 0
77 testpmd> vlan set outer tpid 0x9100 0
83 The Flow Director works in receive mode to identify specific flows or sets of flows and route
84 them to specific queues.
86 The Flow Director filters includes the following types:
89 - 2-tuple filter(destination L4 protocol and destination L4 port)
95 .. code-block:: console
97 ./testpmd -l 4-8 -- i --rxq=4 --txq=4 --pkt-filter-mode=perfect --disable-rss
99 Add a rule to direct packet whose ``ether-type=0x801`` to queue 1:
101 .. code-block:: console
103 testpmd> flow create 0 ingress pattern eth type is 0x801 / end actions queue index 1 / end
105 Add a rule to direct packet whose ``ip-protocol=0x6(TCP), tcp_port=0x80`` to queue 1:
107 .. code-block:: console
109 testpmd> flow create 0 ingress pattern eth / ipv4 proto is 6 / tcp dst is 0x80 / end actions queue index 1 / end
111 Add a rule to direct packet whose ``ip-protocol=0x6(TCP), SYN flag is set`` to queue 1:
113 .. code-block:: console
115 testpmd> flow validate 0 ingress pattern tcp flags spec 0x02 flags mask 0x02 / end actions queue index 1 / end
117 Add a rule to enable ipv4-udp RSS:
119 .. code-block:: console
121 testpmd> flow create 0 ingress pattern end actions rss types ipv4-udp end / end
