[dpdk-dev] [PATCH v2 17/22] net/octeontx: enable port detach on secondary process

[Qi Zhang]

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.
