- * Check if the flow should be splited due to hairpin.
+ * Check if the flow should be split due to hairpin.
  * The reason for the split is that in current HW we can't
- * support encap on Rx, so if a flow have encap we move it
- * to Tx.
+ * support encap and push-vlan on Rx, so if a flow contains
+ * these actions we move it to Tx.
