that it is easier to lock:
- Handle the unsupported ioctl case at the beginning of in_control(),
handing off to ifp->if_ioctl, rather than looking up interfaces and
addresses unnecessarily in this case.
- Make it an invariant that ifp is always non-NULL when running
in_control()-implemented ioctls, simplifying the code structure.

of the object pages, and asserts that object lock is taken. First issue
could cause kernel data corruption, and second one instantly panics the
INVARIANTS-enabled kernel.
Take the advantage of the fact that object->memq is ordered by page index,
and iterate over memq to calculate the runs.
While there, make the code slightly more style-compliant by moving
variables declarations to the right place.

- Ignore DMA tag boundaries when allocating bounce pages. The boundaries
don't determine whether or not parts of a DMA request bounce. Instead,
they are just used to carve up segments.
- Allow tags with sub-page alignment to share bounce pages since bounce
pages are always page aligned.

(1) Don't manually configure if_output(), ether_ifattach() will do that

(2) Call if_detach() before stopping nve in order to prevent calls into

Modify ifioctl() to use ifunit_ref(), holding the reference until
all ioctls, etc, have completed.
This closes a class of reader-writer races in which interfaces
could be removed during long-running ioctls, leading to crashes.
Many other consumers of ifunit() should now use ifunit_ref() to
avoid similar races.

if_alloc(), and portions of data structure destruction from if_detach()
to if_free(). These changes leave more of the struct ifnet in a
safe-to-access condition between alloc and attach, and between detach
and free, and focus on attach/detach as stack usage events rather than
data structure initialization.
Affected fields include the linkstate task queue, if_afdata lock,
address lists, kqueue state, and MAC labels. ifq_attach() ifq_detach()
are not moved as ifq_attach() may use a queue length set by the device
driver between if_alloc() and if_attach().

calls if_free(), and remains set if the refcount is elevated. IF_DYING
skips the bit in the if_flags bitmask previously used by IFF_NEEDSGIANT,
so that an MFC can be done without changing which bit is used, as
IFF_NEEDSGIANT is still present in 7.x.
ifnet_byindex_ref() checks for IFF_DYING and returns NULL if it is set,
preventing new references from by acquired by index, preventing
monitoring sysctls from seeing it. Other lookup mechanisms currently
do not check IFF_DYING, but may need to in the future.

by starting with the first CPU whose APIC ID is after the boot CPU and
wrapping back around to APIC ID 0 if needed rather than always starting
at APIC ID 0. While here, adjust the cpu_mp_announce() routine to list
CPUs based on the mapping established by assign_cpu_ids() rather than
making assumptions about the algorithm assign_cpu_ids() uses.
