+2)  Shared IPv4/IPv6 traffic shaping configuraiton is now
+    available. The device and class configuration can be included in
+    either the Shorewall or the Shorewall6 configuration. To place it
+    in the Shorewall configuration:
+
+    a) Set TC_ENABLED=Internal in shorewall.conf
+    b) Set TC_ENABLED=Shared in shorewall6.conf
+    c) Create symbolic link /etc/shorewall6/tcdevices pointing to
+       /etc/shorewall/tcdevices.
+    d) Create symbolic link /etc/shorewall6/tcclasses pointing to
+       /etc/shorewall/tcclasses.
+    e) Entries for both IPv4 and IPv6 can be included in
+       /etc/shorewall/tcfilters. This file has been extended to allow
+       both IPv4 and IPv6 entries to be included in a single file.
+    f) Packet marking rules are included in both configurations'
+       tcrules file as needed. CLASSIFY rules in
+       /etc/shorewall6/tcrules are validated against the Shorewall TC
+       configuration.
+  
+    In this setup, the tcdevices and tcclasses will only be updated
+    when Shorewall is restarted. The IPv6 marking rules are updated
+    when Shorewall6 is restarted.
+
+    The above configuration may be reversed to allow Shorewall6 to
+    control the TC configuration.
