Bond agnostically interacts with TLS device-offload requests via the .ndo_sk_get_lower_dev operation. Return value is true iff bond guarantees fixed mapping between the TLS connection and a lower netdev. Due to this nature, the bond TLS device offload features are not explicitly controllable in the bond layer. As of today, these are read-only values based on the evaluation of bond_sk_check(). However, this indication might be incorrect and misleading, when the feature bits are "fixed" by some dependency features. For example, NETIF_F_HW_TLS_TX/RX are forcefully cleared in case the corresponding checksum offload is disabled. But in fact the bond ability to still offload TLS connections to the lower device is not hurt. This means that these bits can not be trusted, and hence better become unused. This patch revives some old discussion [1] and proposes a much simpler solution: Clear the bond's TLS features bits. Everyone should stop reading them.

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.
