I just noticed that dev_get_by_index is not hashed, it is just a linear
search through all interfaces. This call is made in many places in the
kernel, and particularly in route.c
For machines with large numbers of interfaces (VLANs for instance),
this could be a real performance drag.
Any reason we don't keep interfaces in a hash-table by index?
