+Identifying Your Adapter
+========================
+For information on how to identify your adapter, and for the latest Intel
+network drivers, refer to the Intel Support website:
+https://www.intel.com/support
+
+
+Command Line Parameters
+========================
+If the driver is built as a module, the following optional parameters are used
+by entering them on the command line with the modprobe command using this
+syntax::
+
+    modprobe igc [<option>=<VAL1>]
+
+NOTE: A descriptor describes a data buffer and attributes related to the data
+buffer. This information is accessed by the hardware.
+
+Debug
+-----
+:Valid Range: 0-16 (0=none,...,16=all)
+:Default Value: 0
+
+This parameter adjusts the level debug messages displayed in the system logs.
+
+
+Additional Features and Configurations
+======================================
+Time-Sensitive Networking
+-------------------------
+Selected models of Intel(R) Ethernet Controller I225 and Intel(R) Ethernet
+Controller I226 support Time-Sensitive Networking features. For more details
+about the features and supported models, please refer to:
+https://www.intel.com/content/www/us/en/support/articles/000096004/ethernet-products/gigabit-ethernet-controllers-up-to-2-5gbe.html
+
+For instructions about configuring Time-Sensitive Networking features on Linux,
+please refer to:
+https://tsn.readthedocs.io/
+
+ethtool
