To this end, callers need to pass struct psref to the functions
and the fuctions acquire a reference of ifp with it. In some cases,
we can simply use if_get_byindex, however, in other cases
(say rt->rt_ifp and ia->ifa_ifp), we have no MP-safe way for now.
In order to take a reference anyway we use non MP-safe function
if_acquire_NOMPSAFE for the latter cases. They should be fixed in
the future somehow.
"expire" value of route get output is unexpectedly a negative value
on rump kernel for some reasons and the tests almost always fail
on babylon5. So just ignore it to make tests work for now. Should
fix it in the future.
a twisty maze of marginal if not illegal type punning it breaks the
cleaner.
This will need to be done over, but it requires substantially more
mechanism and compat ioctls. Booo.
The motivation is the same as the mbuf's rcvif case; avoid having a pointer
of an ifnet object in ip_moptions and ip6_moptions, which is not MP-safe.
ip_moptions and ip6_moptions can be stored in a PCB for inet or inet6
that's life time is different from ifnet one and so an ifnet object can be
disappeared anytime we get it via them. Thus we need to look up an ifnet
object by if_index every time for safe.
while back when I removed a sketchy preprocessor macro scheme, but I'd
left it the way it was at the time and marked it for later. Now I
guess it's later.
Also don't randomly use both dvp and ap->a_dvp; they're the same, so
pick one and stick to it.
