We obviously are not saying that -- hence the existing mechanism for
driver-private tunables.
You're sending some very mixed signals here. On one hand you acknowledge
that the need for these things exists, but on the other hand you refuse
to provide a discovery mechanism for them.
I agree we should *strongly* encourage driver developers to eliminate
tunables where possible. But anyone who has worked with more than one or
two NIC drivers _knows_ that each device may have needs for different
tunables.
Right now the drivers are using ndd and/or driver.conf. If you want them
to use dladm for this stuff, then you need to provide some complete
support, including enumeration support.
