It has occurred to me that I am seeing an implication here that may in fact not
exist.

My impression of dev_get_by_xxxx is that the function is only able to be used
sanely when being part of the definition of a kernel/userspace interface. With
the further assumption on my part that you need to define a new instance of
dev_get_by_xxxx

It has just occurred to me that it is possible to reuse the SIOCBRADDIF
and SIOCBRDELIF for that same purpose without defining a new kernel/userspace
interface.

What and how are you using dev_get_by_xxx?
