When an XDP program is set, a full reopen of all channels happens in two cases: 1. When there was no program set, and a new one is being set. 2. When there was a program set, but it's being unset. The full reopen is necessary, because the channel parameters may change if XDP is enabled or disabled. However, it's performed in an unsafe way: if the new channels fail to open, the old ones are already closed, and the interface goes down. Use the safe way to switch channels instead. The same way is already used for other configuration changes.

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.
