I agree, we should be able to use the description as a means of looking up the interface. However, because descriptions can be arbitrary, you need to have some rules around them:
1- Duplicate descriptions are not allowed (should return EEXIST if an attempt is made to set a duplicate).
2- In order to prevent unpredictable behavior in the presence of name-"wm0" and description-"wm0" being associated with different interfaces, the hardware name should always take priority when looking up an interface.
