[dpdk-dev] [PATCH v7 13/19] net/octeontx: enable port detach on secondary process

[Qi Zhang <qi.z.zhang@intel.com>]

Previously, detach port on secondary process will mess primary
process and cause same device can't be attached again, by take
advantage of rte_eth_release_port_private, we can support this
with minor change.
