+ *
+ * 1. Forwards frames only to ports that are part of the same bridge group and
+ * in the BR_STATE_FORWARDING state.
+ * 2. Takes into account the isolation status of ports; ports in the
+ * BR_STATE_FORWARDING state with BR_ISOLATED configuration will not forward
+ * frames to each other, even if they are in the same bridge group.
+ * 3. Ensures that the CPU port is included in the membership based on its
