It was reported that re-introducing ASPM, in combination with RX interrupt coalescing, results in significantly increased packet latency, see [0]. Disabling ASPM or RX interrupt coalescing fixes the issue. Therefore change the driver's default to disable RX interrupt coalescing. Users still have the option to enable RX coalescing via ethtool.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
