Add new network selftests for the bonding device which exercise the ether type changing call paths. They also test for the recent syzbot bug[1] which causes a warning and results in wrong device flags (IFF_SLAVE missing). The test adds three bond devices and a nlmon device, enslaves one of the bond devices to the other and then uses the nlmon device for successful and unsuccesful enslaves both of which change the bond ether type. Thus we can test for both MASTER and SLAVE flags at the same time. If the flags are properly restored we get: TEST: Change ether type of an enslaved bond device with unsuccessful enslave [ OK ] TEST: Change ether type of an enslaved bond device with successful enslave [ OK ] [1] https://syzkaller.appspot.com/bug?id=391c7b1f6522182899efba27d891f1743e8eb3ef Signed-off-by: Nikolay Aleksandrov <razor@blackwall.org> Reviewed-by: Michal Kubiak <michal.kubiak@intel.com> Acked-by: Jonathan Toppins <jtoppins@redhat.com> Acked-by: Jay Vosburgh <jay.vosburgh@canonical.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.
