Due to the asynchronous nature in which mac filters are added and
deleted, there exists a bug in which filters are erroneously removed if
removed then added again quickly.
The events are as such:
- filter marked for removal
- same filter is re-added before watchdog that cleans up filters
- we skip re-adding the filter because we have it already in the
list
- watchdog filter cleanup kicks off and filter is removed
So when we were re-adding the same filter, it didn't actually get added
because it already existed in the list, but was marked for removal and
had yet to actually be removed.
This patch fixes the issue by making sure that when adding a filter, if
we find it already existing in our list, make sure it is not marked to
be removed.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
