Don't allow joins w/o source on an existing group.
This is almost always pilot error.
We don't need to check for group filter UNDEFINED state at t1,
because we only ever allocate filters with their groups, so we
unconditionally reject such calls with EINVAL.
Trying to change the active filter mode w/o going through IPV6_MSFILTER
is also disallowed.

Tighten input checking in in6p_join_group():
* Don't try to use the source address, when its family is unspecified.
* If we get a join without a source, on an existing inclusive
mode group, this is an error, as it would change the filter mode.
Fix a problem with the handling of in6_mfilter for new memberships:
* Do not rely on im6f being NULL; it is explicitly initialized to a
non-NULL pointer when constructing a membership.
* Explicitly initialize *im6f to EX mode when the source address
is unspecified.
This fixes a problem with in_mfilter slot recycling in the join path.

wired pages have been false for roughly a decade. This and another bug
involving breakpoints will be fixed in coming changes.)

compiled to use Netgraph. This change just makes them always use the

from the build due to TTY changes.
if_watchdog and if_timer. The driver already contained an optional stats
timer that individual attachments could use to provide a 'tick' event. The
stats timer only ran if the tick function pointer was non-NULL and the
attachment's tick routine had to call callout_reset(), etc. Now the driver
always schedules a stat timer and manages the callout_reset() internally.
This timer is used to drive the watchdog and will also call the attachment's
'tick' handler if one is provided.
