Comment (by tomek):

 An extra comment about getIface() and the general way how IfaceMgr stores
 interface info. We may rework it some time in the future to use
 name->object and ifindex->object maps for performance reasons. I'm aware
 of one production deployment that has over 100 interface names (lots of
 vlans), so the performance degradation may be non-trivial in such case. If
 we rework the code, this method may suddenly start returning NULLs.

 One simple "if" is not that big of a deal.
