Hi,
Lagopus switch uses same prefix, "ethX" of interface name in
lagopus.conf, but an interface names in lagopus.conf does not refer
a network interface name that are managed by Linux kernel.
I suppose that your linux machine configuration is as follows:
eth0: linux commnication
eth1: lagopus under DPDK #0
eth2: lagopus under DPDK #1
If you want to use eth1 and eth2 for lagopus with DPDK.
Please specify "-p3" for DPDK option.
> step2. sudo lagopus -d -- -c3 -n1 -- -p6
sudo lagopus -d -- -c3 -n1 -- -p3
In case of "-p6" option, Lagopus tries to enable DPDK #1 and DPDK #2
ports, but there is no DPDK #2 port. As a result, Lagopus may exit
as your log.

Please modify lagopus.conf as follows when two interfaces (eth1 and
eth2 of linux kernel) for Lagopus with DPDK :
===========================lagopus.conf==================================
interface {
ethernet {
eth0;
eth1;
}
}
bridge-domains {
br0 {
port {
eth0;
eth1;
}
controller {
127.0.0.1;
}
}
}
===========================lagopus.conf==================================
These descriptions of lagopus.conf sometimes confuse user, therefore,
we plan to improve way to configure interfaces on Lagopus.
