[dpdk-dev] Cannot run l3fwd with the problem of " nb_tx_queues"

[yuxuan zhang]

 Hi Everyone:

I meet a problem with running the DPDK1.3 example l3fwd in the VMware. 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.
