+    dash marker line as described in Documentation/SubmittingPatches to
+    temporarily embed that information into the patch that you send.
+ 
++Q: Are all networking bug fixes backported to all stable releases?
++
++A: Due to capacity, Dave could only take care of the backports for the last
++   2 stable releases. For earlier stable releases, each stable branch maintainer
++   is supposed to take care of them. If you find any patch is missing from an
++   earlier stable branch, please notify stable@×××××××××××.org with either a
++   commit ID or a formal patch backported, and CC Dave and other relevant
++   networking developers.
++
+ Q: Someone said that the comment style and coding convention is different
+    for the networking content.  Is this true?
