[PATCH v2 0/2] Drivers: hv: vmbus: make bus ids in sysfs persistent

[Vitaly Kuznetsov <vkuznets@redhat.com>]

Bus ids for VMBus devices in /sys/bus/vmbus/devices/ are not guaranteed
to be persistent across reboot or kernel restart and this causes problems
for some tools. E.g. kexec tools use these ids to identify NIC on kdump.
Fix the issue by using if_instance from channel offer as the unique id
instead of an auto incremented counter.

Changes since v1:
- Use if_instance instead of relid [K. Y. Srinivasan]

  Drivers: hv: make VMBus bus ids persistent
