Save per-channel resources in default, in device and host memory. As no better API exist, make the XDP-redirect-target SQ available by loading a dummy XDP program. This improves the latency of interface up/down operations when feature is disabled. Perf numbers: NIC: Connect-X7. Setup: 248 channels, default mtu and rx/tx ring sizes. Interface up + down: Before: 2.246 secs After: 1.798 secs (-0.448 sec) Saves ~1.8 msec per channel.

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.
