# DPDK initialization is done before running os-net-config, to make
# the DPDK ports available when enabled. DPDK Hotplug support is
# supported only in OvS 2.7 version. Until then, OvS needs to be
# restarted after adding a DPDK port. This change will be removed
# on migration to OvS 2.7 where DPDK Hotplug support is available.
