Q counters are device-level counters that track specific events, among which are out_of_buffer events. These events occur when packets are dropped due to a lack of receive buffer in the RX queue. Expose the total number of out_of_buffer events on the VFs/SFs to their respective representor, using the "ip stats group link" under the name of "rx_missed". The "rx_missed" equals the sum of all Q counters out_of_buffer values allocated on the VFs/SFs.

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.
