+IGC Poll Mode Driver
+======================
+
+The IGC PMD (librte_pmd_igc) provides poll mode driver support for
+Foxville and Greenvile I225 Series Network Adapters.
+
+
+Features
+--------
+
+Features of the IGC PMD are:
+
+- Multiple queues for TX and RX
+- Receiver Side Scaling (RSS)
+- MAC/VLAN filtering
+- Packet type information
+- Checksum offload
+- VLAN/QinQ stripping and inserting
+- TSO offload
+- Promiscuous mode
+- Multicast mode
+- Port hardware statistics
+- Jumbo frames
+- Link state information
+- Link flow control
+- Interrupt mode for RX
+- Scattered for RX
+
+
+Config File Options
+~~~~~~~~~~~~~~~~~~~
+
+The following options can be modified in the ``config`` file.
+Please note that enabling debugging options may affect system performance.
+
+- ``CONFIG_RTE_LIBRTE_IGC_PMD`` (default ``y``)
+
+  Toggle compilation of the ``librte_pmd_igc`` driver.
+
+- ``CONFIG_RTE_LIBRTE_IGC_DEBUG_*`` (default ``n``)
+
+  Toggle display of generic debugging messages.
