+/* On page 205, section "8.6.3 Frame filtering" of the active standard, IEEE Std
+ * 802.1Q™-2022, it is stated that frames with 01:80:C2:00:00:00-0F as MAC DA
+ * must only be propagated to C-VLAN and MAC Bridge components. That means
+ * VLAN-aware and VLAN-unaware bridges. On the switch designs with CPU ports,
+ * these frames are supposed to be processed by the CPU (software). So we make
+ * the switch only forward them to the CPU port. And if received from a CPU
+ * port, forward to a single port. The software is responsible of making the
+ * switch conform to the latter by setting a single port as destination port on
+ * the special tag.
+ *
+ * This switch intellectual property cannot conform to this part of the standard
+ * fully. Whilst the REV_UN frame tag covers the remaining :04-0D and :0F MAC
+ * DAs, it also includes :22-FF which the scope of propagation is not supposed
+ * to be restricted for these MAC DAs.
