[dpdk-dev] [PATCH 00/15] bus attach/detach API and hotplug rework

[Jan Blunck]

Following the work from Gaetan, who based his work on my original series.

-- v7

* Revert removal of RTE_VERIFY on find_device operation since a bus that isn't
  able to even iterate its devices is pointless

* Revert plug() changes that have been introduced in v3:
  int (*rte_bus_plug_t)(struct rte_device *dev, const char *devargs);

* Revert pointless reordering of start argument for bus iterator functions

* Add fslmc bus find_device operation

* Add support to find a bus by its name

* Add EAL hotplug API:
  int rte_eal_hotplug_add(const char *busname, const char *devname,
			  const char *devargs);
  int rte_eal_hotplug_remove(const char *busname, const char *devname);

* Keep rte_eal_dev_attach() backwards compatible and support hotplug of PCI
  and virtual devices only

* Add back patch "ethdev: use embedded rte_device to detach driver" which is
  critical for correctly detaching the correct low-level device
