Di Zhu 0ab968d9c5 netdev: preserve NETIF_F_ALL_FOR_ALL across TSO updates
[ Upstream commit 02d1e1a3f9239cdb3ecf2c6d365fb959d1bf39df ]

Directly increment the TSO features incurs a side effect: it will also
directly clear the flags in NETIF_F_ALL_FOR_ALL on the master device,
which can cause issues such as the inability to enable the nocache copy
feature on the bonding driver.

The fix is to include NETIF_F_ALL_FOR_ALL in the update mask, thereby
preventing it from being cleared.

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.
