[dpdk-users] problem using two ports with pktgen-dpdk

Hi,

I'm now simply trying to use two ports in a single pktgen-dpdk instance
(maybe I do not need the two instances...), but still I have a problem

Pktgen Ver: 3.5.1 (DPDK 18.08.0-rc0)
Powered by DPDK ** Version: DPDK 18.08.0-rc0

trying to use two ports as follows, it stops with an error (see below)

sudo -E ./app/x86_64-native-linuxapp-gcc/pktgen  -l 0-4 -n 3 -- -P -m 
"1.0, 2.1"

while using a single port at a time is OK:

sudo -E ./app/x86_64-native-linuxapp-gcc/pktgen  -l 0-4 -n 3  -- -P -m "1.0"

sudo -E ./app/x86_64-native-linuxapp-gcc/pktgen  -l 0-4 -n 3  -- -P -m "2.1"

any suggestion will be appreciated!

ciao Stefano

This is the error, and the full output is further below
