 mechanism that deals with multi-core systems at the first place, not making the
 existing ALTQ MP-safe because it's just annoying.

+Using kernel modules
+--------------------
+
+Please note that if you enable NET_MPSAFE in your kernel, and you use and
+loadable kernel modules (including compat_xx modules or individual network
+interface if_xxx device driver modules), you will need to build custom
+modules.  For each module you will need to add the following line to its
+Makefile:
+
+       CPPFLAGS+=      NET_MPSAFE
+
+Failure to do this may result in unpredictable behavior.
