splnet() surrounding in6_control1()

[Elad Efrat <elad%NetBSD.org@localhost>]

Hi,

In in6_control() there seems to be an splnet() surrounding the call to
in6_control1().

Without going into debate whether or not splnet() around the entire
function is necessary, at the very least it prevents me from using
real kauth(9) calls.

Therefore, I would like to
  - add a switch statement in in6_control(), where we currently issue
the kauth(9) call, and perform the call only for the cases where
in6_control1() checks for the "privileged" variable

  - modify in6_control1() to not take a "privileged" variable anymore,
and instead place a comment ("/* Privileged, see in6_control(). */" or
something) where the variable used to be checked

Are there any objections to such a change?

Thanks,

-e.
