Predictable naming mechanism is leading to issues in DLPAR operations
Status in linux package in Ubuntu:
Status in linux source package in Xenial:
Recent kernels are using predictable naming for network interfaces, so
the network stack is more tied to PCI naming. This can be a problem in
hotplug scenarios, because PCI addresses will change if devices are
removed and then re-added. This situation seems unusual, but it can
happen if a user wants to replace a NIC without rebooting the machine,
The patch attached here should deal with this situation, since it makes PHB/domain number fixed based on device-tree properties.
The problem can be reproduced by removing and re-adding a PCI network adapter, so its address will change and, per predictable naming scheme, so is the interface name.
