Description

OVP7 RCPL 25, with the new dpdk/ovs versions, when bind a NIC to dpdk ovs. The ovs-vswitchd will get segment fault.
And the ovs-vsctl command will stuck all the time.

root@localhost:~# ovs-vsctl add-port br0 dpdk-p0 -- set Interface dpdk-p0 type=dpdk options:dpdk-devargs=0000:45:00.2

Steps to Reproduce

1. project configuration:
/opt/WRL7/wrlinux-7/wrlinux/configure --enable-board=intel-x86-64 --enable-rootfs=ovp-kvm+installer-support --enable-addons=wr-ovp --enable-jobs=8 --enable-parallel-pkgbuilds=8 --enable-reconfig --with-layer=wr-dpdk --enable-bootimage=hdd,tar.bz2 --with-bootimage-space=1024 --enable-checkout-all-layers=yes --enable-rm-oldimgs=yes --with-template=feature/new-dpdk-ovs --with-init=sysvinit --with-rcpl-version=0025

2. Steps below:
root@localhost:~# modprobe uio
root@localhost:~# modprobe igb_uio
root@localhost:~# modprobe rte_kni
root@localhost:~# mkdir /mnt/huge
mkdir: cannot create directory '/mnt/huge': File exists
root@localhost:~# mount -t hugetlbfs nodev /mnt/huge
root@localhost:~# ifconfig eth3 down
root@localhost:~# ifconfig eth4 down
root@localhost:~# /opt/dpdk/share/tools/dpdk_nic_bind.py --bind=igb_uio eth3
root@localhost:~# /opt/dpdk/share/tools/dpdk_nic_bind.py --bind=igb_uio eth4
root@localhost:~# /opt/dpdk/share/tools/dpdk_nic_bind.py --status
