In commitb65969856d("igc: Link queues to NAPI instances"), the XSK queues were incorrectly unmapped from their NAPI instances. After discussion on the mailing list and the introduction of a test to codify the expected behavior, we can see that the unmapping causes the check_xsk test to fail: NETIF=enp86s0 ./tools/testing/selftests/drivers/net/queues.py [...] # Check| ksft_eq(q.get('xsk', None), {}, # Check failed None != {} xsk attr on queue we configured not ok 4 queues.check_xsk After this commit, the test passes: ok 4 queues.check_xsk Note that the test itself is only in net-next, so I tested this change by applying it to my local net-next tree, booting, and running the test.

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.
