if_link.h says: * @rx_dropped: Number of packets received but not processed, * e.g. due to lack of resources or unsupported protocol. * For hardware interfaces this counter may include packets discarded * due to L2 address filtering but should not include packets dropped * by the device due to buffer exhaustion which are counted separately in * @rx_missed_errors (since procfs folds those two counters together). Currently we report "stats->rx_dropped = dev->stats.rx_dropped", the latter being incremented by various entities in the stack. This is not wrong, but we'd like to move ocelot_get_stats64() in the common ocelot switch lib which is independent of struct net_device. To do that, report the hardware RX drop counters instead. These drops are due to policer action, or due to no destinations. When we have no memory in the queue system, report this through rx_missed_errors, as instructed.

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.
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.
