Currently support only default geneve udp port (6081). For the tx side, the HW is assisted by SW parsing, which sets the headers offset to offload tunneled LSO and csum. Note that for udp tunnels, we don't use special rx offloads, as rss on the outer headers is enough, we support checksum complete and GRO takes care of aggregation. Geneve TSO BW and CPU load results (tested using iperf single tcp stream). In this patch we add TSO support over Geneve, so the "before" result doesn't actually get to using the TSO HW offload even when turned on. Tested on ConnectX-5, Intel(R) Xeon(R) CPU E5-2660 v2 @2.20GHz. __________________________________ | Before | After | |________________|_________________| | 12.6 Gbits/sec | 21.7 Gbits/sec | | 100% CPU load | 61.5% CPU load | |________________|_________________| Signed-off-by: Moshe Shemesh <moshe@mellanox.com> Acked-by: Or Gerlitz <ogerlitz@mellanox.com> Signed-off-by: Saeed Mahameed <saeedm@mellanox.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.
