There were two issues with the new pflog packet length.
The first is that the length is expected to be a multiple of
sizeof(long), but we'd assumed it had to be a multiple of
sizeof(uint32_t).
The second is that there's some broken software out there (such as
Wireshark) that makes incorrect assumptions about the amount of padding.
That is, Wireshark assumes there's always three bytes of padding, rather
than however much is needed to get to a multiple of sizeof(long).
Fix this by adding extra padding, and a fake field to maintain
Wireshark's assumption.

Disable Duplicate Address Detection in EC2 instances. The networking

host egress filtering, makes "duplicate addresses" impossible.
This speeds up the boot process in EC2 by 2 seconds.

Merge commit df08b2fe8b35 from llvm git (by Dimitry Andric):
[AArch64] Avoid crashing on invalid -Wa,-march= values
As reported in https://bugs.freebsd.org/260078, the gnutls Makefiles
pass -Wa,-march=all to compile a number of assembly files. Clang does
not support this -march value, but because of a mistake in handling
the arguments, an unitialized Arg pointer is dereferenced, which can
cause a segfault.
Work around this by adding a check if the local WaMArch variable is
initialized, and if so, using its value in the diagnostic message.

When no mask is supplied to the ioctl adding an Internet interface

single default. Similarly for the NFS bootp code.

Similar to netstat, clean up code that uses inet_lnaof() to check for
binding to "host 0" (lowest host on network) as a "network" bind.
Such things don't happen, and current networks are seldom if ever
found in /etc/networks.
(cherry picked from commit a2e7dfca86)
sockstat was checking whether a bound address was "host 0", the lowest
host on a network, using inet_lnaof(). This only works for class A/B/C.
However, it isn't useful to bind such an address unless it is really
the unspecified address INADDR_ANY. Change the check to to use that.
(cherry picked from commit 64acb29b7d)
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.
(cherry picked from commit bd27c71c45)
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.

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.

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.
