Some network drivers use __dev_mc_sync()/__dev_uc_sync() and therefore program the hardware only with addresses with a non-zero sync_cnt. Some of the above drivers also need to save/restore the address filtering lists when certain events happen, and they need to walk through the struct net_device :: uc and struct net_device :: mc lists. But these lists contain unsynced addresses too. To keep the appearance of an elementary form of data encapsulation, provide iterators through these lists that only look at entries with a non-zero sync_cnt, instead of filtering entries out from device drivers.

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.
