Hi Arend, Alexander,
Basically, we now have two bypass methods dealing with the same/similar
issue:
1) bypass the QDISC.
2) bypass network stack entirely with CONTROL_PORT.
It also raises the question in my mind as to why we have two ways of
doing the same thing? From the discussion so far it also sounds like
each requires somewhat different / special handling in the driver.
Wouldn't it make sense to deprecate one and encourage drivers to
implement the other?
CONTROL_PORT was added specifically to take care of the re-keying races
and can be extended with additional attributes over time, as needed
(perhaps for extended key id, etc). Also note that in our testing
CONTROL_PORT is _way_ faster than PAE socket...
Regards,
-Denis
