Wei Fang says: ==================== net: fec: fix some issues of ndo_xdp_xmit() We encountered some issues when testing the ndo_xdp_xmit() interface of the fec driver on i.MX8MP and i.MX93 platforms. These issues are easy to reproduce, and the specific reproduction steps are as follows. step1: The ethernet port of a board (board A) is connected to the EQOS port of i.MX8MP/i.MX93, and the FEC port of i.MX8MP/i.MX93 is connected to another ethernet port, such as a switch port. step2: Board A uses the pktgen_sample03_burst_single_flow.sh to generate and send packets to i.MX8MP/i.MX93. The command is shown below. ./pktgen_sample03_burst_single_flow.sh -i eth0 -d 192.168.6.8 -m \ 56:bf:0d:68:b0:9e -s 1500 step3: i.MX8MP/i.MX93 use the xdp_redirect bfp program to redirect the XDP frames from EQOS port to FEC port. The command is shown below. ./xdp_redirect eth1 eth0 After a few moments, the warning or error logs will be printed in the console, for more details, please refer to the commit message of each patch. ==================== Link: https://lore.kernel.org/r/20230706081012.2278063-1-wei.fang@nxp.com Signed-off-by: Paolo Abeni <pabeni@redhat.com> |

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.
