Just RX and TX packet counts and TX bytes for now. We do not have per-queue RX byte counts, which causes us to fail stats.pkt_byte_sum selftest with "Drivers should always report basic keys" error. Per-queue counts are since the last time the queue was inited (typically by efx_start_datapath(), on ifup or reconfiguration); device-wide total (efx_get_base_stats()) is since driver probe. This is not the same lifetime as rtnl_link_stats64, which uses firmware stats which count since FW (re)booted; this can cause a "Qstats are lower" or "RTNL stats are lower" failure in stats.pkt_byte_sum selftest. Move the increment of rx_queue->rx_packets to match the semantics specified for netdev per-queue stats, i.e. just before handing the packet to XDP (if present) or the netstack (through GRO). This will affect the existing ethtool -S output which also reports these counters. XDP TX packets are not yet counted into base_stats.

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.
