Identifying Your Adapter
========================

The driver in this release is compatible with AQC-100, AQC-107, AQC-108
based ethernet adapters.


SFP+ Devices (for AQC-100 based adapters)
-----------------------------------------

This release tested with passive Direct Attach Cables (DAC) and SFP+/LC
Optical Transceiver.

Configuration
=============

Viewing Link Messages
---------------------
  Link messages will not be displayed to the console if the distribution is
  restricting system messages. In order to see network driver link messages on
  your console, set dmesg to eight by entering the following::

       dmesg -n 8

  .. note::

     This setting is not saved across reboots.

Jumbo Frames
------------
  The driver supports Jumbo Frames for all adapters. Jumbo Frames support is
  enabled by changing the MTU to a value larger than the default of 1500.
  The maximum value for the MTU is 16000.  Use the `ip` command to
  increase the MTU size.  For example::

	ip link set mtu 16000 dev enp1s0

ethtool
-------
  The driver utilizes the ethtool interface for driver configuration and
  diagnostics, as well as displaying statistical information. The latest
  ethtool version is required for this functionality.

NAPI
----
  NAPI (Rx polling mode) is supported in the atlantic driver.

Supported ethtool options
