The proposal to merge ~smoser/cloud-init:bug/1669860-no-rename-bonds into cloud-init:master has been updated.

Commit Message changed to:

Fix bug that resulted in an attempt to rename bonds or vlans.

When cloud-init ran in the init stage (after networking had come up).
A bug could occur where cloud-init would attempt and fail to rename
network devices that had "inherited" mac addresses.

The intent of apply_network_config_names was always to rename only
the devices that were "physical" per the network config.  (This would
include veth devices in a container).  The bug was in creating
the dictionary of interfaces by mac address.  If there were multiple
interfaces with the same mac address then renames could fail.
This situation was guaranteed to occur with bonds or vlans or other
devices that inherit their mac.

The solution is to change get_interfaces_by_mac to skip interfaces
that have an inherited mac.
