[dpdk-users] l3fwd rte_eth_rx_queue_setup: err=-22

[Rosen, Rami]

Hello, Chris,

First, there are several places in the rte_eth_rx_queue_setup() method where -22 (-EINVAL) is returned.
See: http://dpdk.org/browse/dpdk/tree/lib/librte_ether/rte_ethdev.c#n1083

I would suggest, as a first step,  that you will build dpdk with debug info for this method:
change CONFIG_RTE_LIBRTE_ETHDEV_DEBUG to be y in build/.config, and then run 
make clean and make, and then please run the l3fwd app again; if there is additional info in the log, please post it here if the info still does not help you solve the problem, as it might give a hint. Also please tell which DPDK version you are using.

Regards,
Rami Rosen

Hello,

I’m having a bit of trouble running the l3fwd example program, I keep getting the error “rte_eth_rx_queue_setup: err=-22”
No matter what options I supply. Wondering if I’m missing something ?

Using l3fwd from dpdk-next-net

Thanks in advance.
Chris
