Laurent Vivier says: ==================== virtio_net: vdpa: update MAC address when it is generated by virtio-net When the MAC address is not provided by the vdpa device virtio_net driver assigns a random one without notifying the device. The consequence, in the case of mlx5_vdpa, is the internal routing tables of the device are not updated and this can block the communication between two namespaces. To fix this problem, use virtnet_send_command(VIRTIO_NET_CTRL_MAC) to set the address from virtnet_probe() when the MAC address is not provided by the device. ==================== Link: https://lore.kernel.org/r/20230127204500.51930-1-lvivier@redhat.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 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.
