Fix requiring device-number on EC2 derivatives (#836)
|
||||
|
||||
#342 (70dbccbb) introduced the ability to determine route-metrics based on
|
||||
the `device-number` provided by the EC2 IMDS. Not all datasources that
|
||||
subclass EC2 will have this attribute, so allow the old behavior if
|
||||
`device-number` is not present.
