I've continued the work done by Shreyansh for bus abstraction and PCI implementation. This change has two benefits: - ease future introduction of new bus - clean existing buses (only PCI here) The same kind of work must be done on VDEV in order to move these implementations as bus drivers.
changes in v11: - fixes for BSD - remove useless bus object retrieving - remove useless bus reference in rte_device - some rewording and patch reordering Unfortunately, it is not ready to be integrated in 17.02. More specifically: - the tests need some review/rework - the PCI implementation requires more work - the documentation must be updated However there are some new buses waiting for the bus abstraction, which is simple and good enough. That's why I have isolated the generic bus model in first patches and will apply them in 17.02-rc1. It will allow to base new buses on top of rte_bus.
