This new bus takes as devices kernel netdevices.
It offers an API for drivers to register a translation layer that would
transform the netdev name to one their regular PMD would be able to
probe.
This is PoC. It currently only works for MLX4 and MLX5 PMDs as they were
bifurcated and had very little work to do otherwise.
The planned feature is for at least all PCI drivers, be able to unbind
the device from its kmod and bind it to a choosen IO module, prior to
probing.
Additional possible feature would be a close integration with eventually
NCI-like lib, to transparently capture kernel devices, keep a control
interface present and bind / unbind the underlying hardware function as
necessary.
This bus depends on plug / unplug being implemented for the sub-bus
(here, PCI or vdev). If new buses wants to be able to capture kernel
netdevices this way, they should implement plug / unplug.
This patchset depends on:
