Hello community
I'm trying to run the test-dpdkr application but it causes
segmentation fault in ovs-vswitchd as below.
Aug 2 21:48:32 ulak ovs-vsctl: ovs|00001|vsctl|INFO|Called as
ovs-vsctl add-port br0 dpdkr0 -- set Interface dpdkr0 type=dpdkr

/home/ulak/ovs-master/lib/dp-packet.h:718
First, I tried OvS 2.11.0 and DPDK 18.11.2 version written on OVS
releases, but the same seqfault was there, then I used the latest OVS
and DPDK (it has a build error for RTE_COLOR_GREEN, I fixed it), and
still the same problem
root@ulak:/home/ulak# ovs-vswitchd --version
ovs-vswitchd (Open vSwitch) 2.12.90
DPDK 19.05.0
I just followed the steps in [1], and this problem arises every time,
my setup is as follows:
root@ulak:/home/ulak# ovs-vsctl show

Last, I was using the test-dpdkr without any problem with the OvS version 2.7.
Thanks in advance..
