Guys,

Do we have a clear criteria when it makes sense to have debugfs for
network driver and when it doesn't, for example
we got this cold shower
http://marc.info/?l=linux-netdev&m=135959539719935&w=2 when attempting
to do so and I am
not fully clear (or want to sharpen the sow) how to review a concrete
design/need for debugs to fall into yes, it makes sense, or
no, it doesn't b/c there are existing mechanisms that can be used or
extended for that matter.

Or.
