When attempting to characterize bound addresses, netstat was checking
for host 0 on a (historical) net using inet_lnaof(). Such addresses
are not normally bound, as they would not work, with the exception
of the unspecified address, INADDR_ANY. Check for that explicitly.
Similarly, don't check bound addresses for a match to a network name.

The exports file format allows export to a network using an explicit
mask or prefix length (CIDR). It also allows a network with just
a dotted address, in which case the historical mask was used.
Deprecate this usage, and warn when it is used. Document that this
is deprecated.
(cherry picked from commit 92aebdeaff)
Mark functions inet_netof(), inet_lnaof(), and inet_makeaddr() as
deprecated, as they assume Class A/B/C. inet_makeaddr() mostly works
when networks are a multiple of 8 bits, but warn for anything other
than historical classes. Reduce other mentions of network classes.
(cherry picked from commit 12bd931d8c)
Add a postproc function for af_inet, and add interface flags as a
parameter. Check there if setting an address without a mask unless
the interface is loopback or point-to-point, where mask is not really
meaningful; warn if so. This will hopefully be an error in the future.
(cherry picked from commit d8237b9555)
Hide historical Class A/B/C macros unless IN_HISTORICAL_NETS is defined;
define it for user level. Define IN_MULTICAST separately from IN_CLASSD,
and use it in pf instead of IN_CLASSD. Stop using class for setting
default masks when not specified; instead, define new default mask
(24 bits). Warn when an Internet address is set without a mask.

iflib_stop modifies iflib data structures that are used by _task_fn_rx,
most prominently the free lists. So, iflib_stop has to ensure that the
rx task threads are not active.
This should help to fix a crash seen when iflib_if_ioctl (e.g.,
SIOCSIFCAP) is called while there is already traffic flowing.
The crash has been seen on VMWare guests with vmxnet3 driver.
My guess is that on physical hardware the couple of 1ms delays that
iflib_stop has after disabling interrupts are enough for the queued work
to be completed before any iflib state is touched.
But on busy hypervisors the guests might not get enough CPU time to
complete the work, thus there can be a race between the taskqueue
threads and the work done to handle an ioctl, specifically in iflib_stop
and iflib_init_locked.

twsi_error() is a new function that stops the current transfer and sets
up softc when an error condition is detected.
TWSI_STATUS_DATA_WR_NACK, TWSI_STATUS_BUS_ERROR and
TWSI_STATUS_ARBITRATION_LOST are now handled explicitly rather than
via the catch-all unknown status.
Also, twsi_intr() now calls wakeup() in a single place when the
transfer is finished.
(cherry picked from commit a4fe892208)
All accesses to softc are now done under a mutex to prevent data races
between the open context and the interrupt handler.
Additionally, the wait time in twsi_transfer is bounded now.
Previously we could get stuck there forever if an interrupt got lost.

When sending packets the stcb was used to access the inp and then
access the endpoint specific IPv6 level options. This fails when
there exists an inp, but no stcb yet. This is the case for sending
an INIT-ACK in response to an INIT when no association already
exists. Fix this by just providing the inp instead of the stcb.

Section 9.5 of RFC 6458 (SCTP Socket API) requires that

is the cause of reporting 0 addresses. So don't indicate an

As in 73db3b64f1, when WITHOUT_INET6 is selected, null if-then-else

Moving the #if statements reduces unnecessary runtime comparisons or
