Some DPDK applications wrongly assume these requirements:
- no hotplug, i.e. ports are never detached
- all allocated ports are available to the application
Such application assume a valid port index is in the range [0..count[.
There are three consequences when using such wrong design:
- new ports having an index higher than the port count won't be valid
- old ports being detached (RTE_ETH_DEV_UNUSED) can be valid
Such mistake will be less common with growing hotplug awareness.
All applications and examples inside this repository - except testpmd -
must be fixed to use the function rte_eth_dev_is_valid_port.
