 /* Decide whether to transmit using ALR lookup, or transmit directly to
  * port using tag. ALR learning is performed only when using ALR lookup.
- * If the two external ports are bridged and the packet is not STP BPDU,
+ * If the two external ports are bridged and the frame is unicast,
  * then use ALR lookup to allow ALR learning on CPU port.
  * Otherwise transmit directly to port with STP state override.
