There was a change previously to stop SR-IOV and LAG from existing on the same interface. This was to prevent the violation of LACP (Link Aggregation Control Protocol). The method to achieve this was to add a no-op Rx handler onto the netdev when SR-IOV VFs were present, thus blocking bonding, bridging, etc from claiming the interface by adding its own Rx handler. Also, when an interface was added into a aggregate, then the SR-IOV capability was set to false. There are some users that have in house solutions using both SR-IOV and bridging/bonding that this method interferes with (e.g. creating duplicate VFs on the bonded interfaces and failing between them when the interface fails over). It makes more sense to provide the most functionality possible, the restriction on co-existence of these features will be removed. No additional functionality is currently being provided beyond what existed before the co-existence restriction was put into place. It is up to the end user to not implement a solution that would interfere with existing network protocols.

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.
