Ronak Doshi says: ==================== vmxnet3: upgrade to version 4 vmxnet3 emulation has recently added several new features which includes offload support for tunnel packets, support for new commands the driver can issue to emulation, change in descriptor fields, etc. This patch series extends the vmxnet3 driver to leverage these new features. Compatibility is maintained using existing vmxnet3 versioning mechanism as follows: - new features added to vmxnet3 emulation are associated with new vmxnet3 version viz. vmxnet3 version 4. - emulation advertises all the versions it supports to the driver. - during initialization, vmxnet3 driver picks the highest version number supported by both the emulation and the driver and configures emulation to run at that version. In particular, following changes are introduced: Patch 1: This patch introduces utility macros for vmxnet3 version 4 comparison and updates Copyright information. Patch 2: This patch implements get_rss_hash_opts and set_rss_hash_opts methods to allow querying and configuring different Rx flow hash configurations which can be used to support UDP/ESP RSS. Patch 3: This patch introduces segmentation and checksum offload support for encapsulated packets. This avoids segmenting and calculating checksum for each segment and hence gives performance boost. Patch 4: With all vmxnet3 version 4 changes incorporated in the vmxnet3 driver, with this patch, the driver can configure emulation to run at vmxnet3 version 4. Changes in v3 -> v4: - Replaced BUG_ON() with WARN_ON_ONCE() Changes in v2 -> v3: - fixed get_rss_hash_opts to return correct values for udp rss Changes in v2: - Fixed compilation issue due to missing closed brace - added fallthrough comment ==================== Signed-off-by: David S.

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.
