If a bonding device has slave devices, then the current logic to derive the feature set for the master bond device is limited in that flags which are fully supported by the underlying slave devices cannot be propagated up to vlan devices which sit on top of bond devices. Instead, these get blindly masked out via current NETIF_F_ALL_FOR_ALL logic. vlan_features and mpls_features should reuse netdev_base_features() in order derive the set in the same way as ndo_fix_features before iterating through the slave devices to refine the feature set.

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.
