- * Load the virtual address for Rx WQE. non-x86 processors
- * (mostly RISC such as ARM and Power) are more vulnerable to
- * load stall. For x86, reducing the number of instructions
- * seems to matter most.
+ * In order to support the mbufs with external attached
+ * data buffer we should use the buf_addr pointer instead of
+ * rte_mbuf_buf_addr(). It touches the mbuf itself and may
+ * impact the performance.
