Reorganize the "Kernel Changes" section, including:
- Add "Hardware Support" section and move device driver-related items there. - Move "Multimedia Support" and "Network Interface Support" into the "Hardware Support" section as sub-sections. - Move Netgraph-related items to "Network Protocols". For translators: many items are moved but the contents are not changed.

<para>The &man.sound.4; (formerly &man.pcm.4;) driver has been modified to read
|
||||
<filename>/boot/device.hints</filename> on startup, to allow setting
|
||||
of default values for mixer channels.
|
||||
Note that currently the device driver's name used in
|
||||
<filename>/boot/device.hints</filename> is still <literal>pcm</literal>.

More detailed information and examples can be found in the &man.sound.4;
|

manual page.</para>

<para>The SMBFS client now has support for SMB request signing,
|
||||
which prevents <quote>man in the middle</quote> attacks and is
|
||||
required in order to connect to Windows 2003 servers in their
|
||||
default configuration. As signing each message imposes a
|
||||
significant performance penalty, this feature is only enabled
|
||||
if the server requires it; this may eventually become an
|
||||
option to &man.mount.smbfs.8;.</para>
