The em28xx driver never touched the EM2874 register bits that control the transport stream packet filters, leaving them at whatever default the firmware has set. E.g. the Pinnacle 290e disables them by default, while the Hauppauge WinTV dualHD enables discarding NULL packets by default. However, some applications require NULL packets, e.g. to determine the load in DOCSIS segments, so discarding NULL packets is undesired for such applications. This patch simply extends the bit mask when starting or stopping the transport stream packet capture, so that the filter bits are cleared. It has been verified that this makes the Hauppauge WinTV dualHD pass an unfiltered DVB-C stream including NULL packets, which it didn't before.

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.
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.
