Subject: [dpdk-users] l3fwd rte_eth_dev_configure: err=-17
Date: Sun, 30 Jul 2017 15:42:58 +0800 (GMT+08:00)	[thread overview]
Message-ID: <3fad13ce.3372.15d9272b7df.Coremail.czy12345@mail.ustc.edu.cn> (raw)

Hello experts,

I have successfully ran l2fwd example. But I'm having troubles running the l3fwd example. I find that in l2fwd the nb_tx_queue parameter of function rte_eth_dev_configure is equal to 1, but in l3fwd the parameter is set to the number of lcores. And then when I use more than one lcores, the function fails. Wondering what is related with the problem?

Thanks in advance.

#./l3fwd -l 1 -n 4 -- -p 0x3 --config="(0,0,1),(1,0,1)" --parse-ptype
success

#./l3fwd -l 1,2 -n 4 -- -p 0x3 --config="(0,0,1),(1,0,2)" --parse-ptype
