Sending those fixes as separate patches as they stand on their own. This series improves usability of the hotplug API and fixes a few issues with existing implementations.
The hotplug API can be tested with the fail-safe PMD[1]. Its documentation describes how to declare slaves and how to use it. [1]: http://dpdk.org/ml/archives/dev/2017-July/070529.html v2: - Add a new rte_devargs function taylored for hotplug operations. Upon device hotplug, the device is implicitly whitelisted. This configuration should supersede any previous existing bus configuration. - Merge hotplug add and remove fixes as they are now tied up. - Do not return an rte_device handle back from hotplug_add. v3: - Further explain - the new rte_eal_devargs_insert function. - the hotplug add / remove fix - the PCI device name fix - Add comments to pci_name_set v4: - Free rte_devargs after the device is being removed, to avoid risks of buses relying on the rte_devargs during the process.
