Hi team,
Currently I am using DPDK version 1.2, for which can I configure
VMDQ_DCB both in Rx/Tx Mq modes ?
In v1.2 I see only Rx MQ mode is defined but not Tx as below.
Does it mean application can only receive packets from multiple traffic
classes but not transmit ?
If yes, do I need to upgrade my DPDK to latest release ?
205 enum rte_eth_rx_mq_mode {
206 ETH_RSS = 0, /**< Default to RSS mode */
207 ETH_VMDQ_DCB /**< Use VMDQ+DCB to route traffic to queues */
208 };
However in later release v1.6 has both Rx & Tx MQ mode independently as
shown below,
248 enum rte_eth_rx_mq_mode {
249 ETH_MQ_RX_NONE = 0, /**< None of DCB,RSS or VMDQ mode */
250
251 ETH_MQ_RX_RSS, /**< For RX side, only RSS is on */
252 ETH_MQ_RX_DCB, /**< For RX side,only DCB is on. */
253 ETH_MQ_RX_DCB_RSS, /**< Both DCB and RSS enable */
254
255 ETH_MQ_RX_VMDQ_ONLY, /**< Only VMDQ, no RSS nor DCB */
256 ETH_MQ_RX_VMDQ_RSS, /**< RSS mode with VMDQ */
257 ETH_MQ_RX_VMDQ_DCB, /**< Use VMDQ+DCB to route traffic to
queues */
258 ETH_MQ_RX_VMDQ_DCB_RSS, /**< Enable both VMDQ and DCB in
VMDq */
259 };
268 /**
269 * A set of values to identify what method is to be used to transmit
270 * packets using multi-TCs.
271 */
272 enum rte_eth_tx_mq_mode {
273 ETH_MQ_TX_NONE = 0, /**< It is in neither DCB nor VT
mode. */
274 ETH_MQ_TX_DCB, /**< For TX side,only DCB is on. */
275 ETH_MQ_TX_VMDQ_DCB, /**< For TX side,both DCB and VT is on. */
276 ETH_MQ_TX_VMDQ_ONLY, /**< Only VT on, no DCB */
277 };
Thanks,
Sunil
