The RTE_ALIGN macro is aligned upwards. If the buf_size variable is not aligned with 1 << I40E_RXQ_CTX_DBUFF_SHIFT, the rx_buf_len is larger than the actual mbuf memory after the operation. When receiving the packet, if the packet is larger than the configured buf_size, it will cause a memory stepping event. The patch uses the RTE_ALIGN_FLOOR down alignment macro to correct the problem.
