commit 427db97df1ee721c20bdc9a66db8a9e1da719855 upstream.
The tx_aborted_errors statistic should count packets flagged with EXD,
EXC, FU, or BCM bits because those bits denote an aborted transmission.
That corresponds to the bitmask 0x0446, not 0x0642. Use macros for these
constants to avoid mistakes. Better to leave out FIFO Underruns (FU) as
there's a separate counter for that purpose.
Don't lump all these errors in with the general tx_errors counter as
that's used for tx timeout events.
On the rx side, don't count RDE and RBAE interrupts as dropped packets.
These interrupts don't indicate a lost packet, just a lack of resources.
When a lack of resources results in a lost packet, this gets reported
in the rx_missed_errors counter (along with RFO events).
Don't double-count rx_frame_errors and rx_crc_errors.
Don't use the general rx_errors counter for events that already have
special counters.

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.
