I have two 82545EM NIC to run the l3fwd and the OS is Cent6.4. But l3fwd cannot be configured port correctly .I start the l3fwd with following command: ./build/l3fwd -c 0x3 -n 2 -- -p 0x3 --config="(0,0,0),(1,0,1)" However, I get following errors with debug info: Initializing port 0 ... Creating queues: nb_rxq=1 nb_txq=2... PMD: rte_eth_dev_configure: ethdev port_id=0 nb_tx_queues=2 > 1 EAL: Error - exiting with code: 1 Cause: Cannot configure device: err=-22, port=0 And I have known that the reason for this problem produced in the **rte_eth_dev_configure function**. However, I do not kown how to fix it. I would really appreciate If someone could provide some help to solve this issue. ^ permalink raw reply [flat|nested] 6+ messages in thread

I guess may DPDK don't support the chip-set so that we got this error msg. In my system, I have 2 kinds of chip-set, 82580 & 82574L. If I use l3fwd -c 3 -n 1 -- -p 3 --config '(0,0,0),(1,0,1)' in 82574L, it will get the error msg. But when I change my card with 82580 and use the same command to execute DPDK l3fwd. It's working. So, maybe the root cause is the DPDK does not support your chip-set and send out this error msg.

No, it's only a problem of hardware queues availability. 82574 has only 1 queue. -- Thomas ^ permalink raw reply [flat|nested] 6+ messages in thread

I'm not totally sure about the capabilities of the e1000 NIC but based on the error you've mentioned, it seems that it can only support 1 TX queue. "Now, I can use only one logic core to run the app and the performance of l3fwd is undesirable." This shows that dpdk can run successfully with 1 TX queue only because probably your e1000 NIC only supports 1 queue.
