Instead of rather verbose comparison of current netdev->features bits vs the incoming ones from user, let us compress them by a helper features set that will be the result of netdev->features XOR features. This way, current, extensive branches: if (features & NETIF_F_BIT && !(netdev->features & NETIF_F_BIT)) set_feature(true); else if (!(features & NETIF_F_BIT) && netdev->features & NETIF_F_BIT) set_feature(false); can become: netdev_features_t changed = netdev->features ^ features; if (changed & NETIF_F_BIT) set_feature(!!(features & NETIF_F_BIT)); This is nothing new as currently several other drivers use this approach, which I find much more convenient.

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.
