Jay Jayatheerthan says: ==================== This series of patches enhances xdpsock application with command line parameters to set transmit packet size and fill pattern among other options. The application has also been enhanced to use Linux Ethernet/IP/UDP header structs and calculate IP and UDP checksums. I have measured the performance of the xdpsock application before and after this patch set and have not been able to detect any difference. Packet Size: ------------ There is a new option '-s' or '--tx-pkt-size' to specify the transmit packet size. It ranges from 47 to 4096 bytes. Default packet size is 64 bytes which is same as before. Fill Pattern: ------------- The transmit UDP payload fill pattern is specified using '-P' or '--tx-pkt-pattern'option. It is an unsigned 32 bit field and defaulted to 0x12345678. Packet Count: ------------- The number of packets to send is specified using '-C' or '--tx-pkt-count' option. If it is not specified, the application sends packets forever. Batch Size: ----------- The batch size for transmit, receive and l2fwd features of the application is specified using '-b' or '--batch-size' options. Default value when this option is not provided is 64 (same as before). Duration: --------- The application supports '-d' or '--duration' option to specify number of seconds to run. This is used in tx, rx and l2fwd features. If this option is not provided, the application runs for ever. ==================== Tested-by: Björn Töpel <bjorn.topel@intel.com> Acked-by: Björn Töpel <bjorn.topel@intel.com> Signed-off-by: Alexei Starovoitov <ast@kernel.org>
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.
