This is enabled by default in other Intel drivers I've checked (e1000, e1000e, iavf, igb and ice). Fixes an out-of-the-box performance issue when running OpenWrt on typical mini-PCs with igc-supported Ethernet controllers and 802.1Q VLAN configurations, as ethtool isn't part of the default packages and sane defaults are expected. In my specific case, with an Intel N100-based machine with four I226-V Ethernet controllers, my upload performance increased from under 30 Mb/s to the expected ~1 Gb/s.

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 reStructuredText 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.
