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 iterates over ports by its own mean.
The most common pattern is to request the port count and
assume ports with index in the range [0..count[ can be used.
There are three consequences when using such wrong design:
- new ports having an index higher than the port count won't be seen
- old ports being detached (RTE_ETH_DEV_UNUSED) can be seen as ghosts
- failsafe sub-devices (RTE_ETH_DEV_DEFERRED) will be seen by the application
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 iterator RTE_ETH_FOREACH_DEV.
