The Receive Frame Rejected interrupt is asserted whenever there was a receive error (bad FCS, bad length, etc.) or whenever the frame was dropped due to a mismatched address. So this is really a combination of rx_otherhost_dropped, rx_length_errors, rx_frame_errors, and rx_crc_errors. Mismatched addresses are common and aren't really errors at all (much like how fragments are normal on half-duplex links). To avoid confusion, report these events as rx_dropped. This better reflects what's going on: the packet was received by the MAC but dropped before being processed.

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.
