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

Annotation
- Atlas domain: Support Tooling And Documentation / Documentation.
- Implementation status: atlas-only.
Implementation Notes
- This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
- Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
- Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
