Linux kernel source tree
2c5ffe8d72
Enslaving of front panel ports (and their uppers) to netdevices that already have uppers is currently forbidden. In the previous patches, a number of replays have been added. Those ensure that various bits of state, such as next hops or switchdev objects, are offloaded when they become relevant due to a mlxsw lower being introduced into the topology. However the act of actually, for example, enslaving a front-panel port to a bridge with uppers, has been vetoed so far. In this patch, remove the vetoes and permit the operation. mlxsw currently validates creation of "interesting" uppers. Thus creating VLAN netdevices on top of 802.1ad bridges is forbidden if the bridge has an mlxsw lower, but permitted in general. This validation code never gets run when a port is introduced as a lower of an existing netdevice structure. Thus when enslaving an mlxsw netdevice to netdevices with uppers, invoke the PRECHANGEUPPER event handler for each netdevice above the one that the front panel port is being enslaved to. This way the tower of netdevices above the attachment point is validated. Signed-off-by: Petr Machata <petrm@nvidia.com> Reviewed-by: Danielle Ratson <danieller@nvidia.com> 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.
