[PATCH net-next 4/4] selftests: drv-net: validate the environment

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Throw a slightly more helpful exception when env variables
are partially populated. Prior to this change we'd get
a dictionary key exception somewhere later on.
