The driver supports pause frames,
but does not pass pause frames based on rx pause enable configuration,
resulting in incorrect pause frame statistics.
like this:
mz eno3 '01 80 c2 00 00 01 00 18 2d 04 00 9c 88 08 00 01 ff ff' \
-p 64 -c 100
ethtool -S enp132s0f2 | grep -v ": 0"
NIC statistics:
rx_octets_total_filt_cnt: 6800
rx_filt_pkt_cnt: 100
The rx pause frames are filtered by the MAC hardware.
This patch configures pass pause frames based on the
rx puase enable status to ensure that
rx pause frames are not filtered.
mz eno3 '01 80 c2 00 00 01 00 18 2d 04 00 9c 88 08 00 01 ff ff' \
-p 64 -c 100
ethtool --include-statistics -a enp132s0f2
Pause parameters for enp132s0f2:
Autonegotiate: on
RX: on
TX: on
RX negotiated: on
TX negotiated: on
Statistics:
tx_pause_frames: 0
rx_pause_frames: 100

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.
