Expose per-queue stats for ethtool -S.
As there are only rx queues, and rx queues are used only when XDP is
used, per-queue counters are only rx XDP ones.
Example:
$ ethtool -S veth0
NIC statistics:
peer_ifindex: 11
rx_queue_0_xdp_packets: 28601434
rx_queue_0_xdp_bytes: 1716086040
rx_queue_0_xdp_drops: 28601434
rx_queue_1_xdp_packets: 17873050
rx_queue_1_xdp_bytes: 1072383000
rx_queue_1_xdp_drops: 17873050

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
