In order to avoid all table update, and only remove or add new address, the auxiliary function exists, named __hw_addr_sync_dev(). It allows end driver do nothing when nothing changed and add/rm when concrete address is firstly added or lastly removed. But it doesn't include cases when an address of real device or vlan was reused by other vlans or vlan/macval devices. For handaling events when address was reused/unreused the patch adds new auxiliary routine - __hw_addr_ref_sync_dev(). It allows to do nothing when nothing was changed and do updates only for an address being added/reused/deleted/unreused. Thus, clone address changes for vlans can be mirrored in the table. The function is exclusive with __hw_addr_sync_dev(). It's responsibility of the end driver to identify address vlan device, if it needs so.

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.
