Ronak Doshi says: ==================== vmxnet3: upgrade to version 9 vmxnet3 emulation has recently added timestamping feature which allows the hypervisor (ESXi) to calculate latency from guest virtual NIC driver to all the way up to the physical NIC. This patch series extends vmxnet3 driver to leverage these new feature. 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 9. - 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 9 comparison and updates Copyright information. Patch 2: This patch adds support to timestamp the packets so as to allow latency measurement in the ESXi. Patch 3: This patch adds support to disable certain offloads on the device based on the request specified by the user in the VM configuration. Patch 4: With all vmxnet3 version 9 changes incorporated in the vmxnet3 driver, with this patch, the driver can configure emulation to run at vmxnet3 version 9. ==================== Link: https://lore.kernel.org/r/20240531193050.4132-1-ronak.doshi@broadcom.com Signed-off-by: Jakub Kicinski <kuba@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 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.
