reporting - in my previous change, I missed the case where a mbuf
from the packet zone was freed back to the mbuf/packet keg, where
it was subsequently put into the mbuf zone and found not to contain
the expected trash. This change adds the necessary trash_dtor call inside
mb_fini_pack so that everything is correct.
Thanks for Bosko for finding the bug and showing me how secondary zones
work.

route itself.
It fixes a bug where an IPv4 route for example has an IPv6 gateway
specified:
route add 10.1.1.1 -inet6 fe80::1%fxp0
Destination Gateway Flags Refs Use Netif Expire
10.1.1.1 fe80::1%fxp0 UGHS 0 0 fxp0
The fix rejects these illegal combinations:
route: writing to routing socket: Invalid argument
add host 10.1.1.1: gateway fe80::1%fxp0: Invalid argument

which command to use to read the eeprom and which devices have an MII.
Simplify code by no longer using the OLDCARD compat rouintes (I don't
know if this breaks OLDCARD on pc98 or not, but OLDCARD on pc98 days
are numbered, I hope). This also removes a number of kludges that we
had before because they are OBE. Add a convenience routine to lookup
the device to avoid many casts in many places.

immediate is not saved by the architecture. Any of the break.{mifx}
instructions have their immediate saved in cr.iim on interruption.
Consequently, when we handle the break interrupt, we end up with a
break value of 0 when it was a break.b. The immediate is important
because it distinguishes between different uses of the break and
which are defined by the runtime specification.
The bottomline is that when the GNU debugger replaces a B-unit
instruction with a break instruction in the inferior, we would not
send the process a SIGTRAP when we encounter it, because the value
is not one we recognize as a debugger breakpoint.
This change adds logic to decode the bundle in which the break
instruction lives whenever the break value is 0. The assumption
being that it's a break.b and we fetch the immediate directly out
of the instruction. If the break instruction was not a break.b,
but any of break.{mifx} with an immediate of 0, we would be doing
unnecessary work. But since a break 0 is invalid, this is not a
problem and it will still result in a SIGILL being sent to the
process.

kernel module. LibAlias is not aware about checksum offloading,
so the caller should provide checksum calculation. (The only
current consumer is ng_nat(4)). When TCP packet internals has
been changed and it requires checksum recalculation, a cookie
is set in th_x2 field of TCP packet, to inform caller that it
needs to recalculate checksum. This ugly hack would be removed
when LibAlias is made more kernel friendly.
Incremental checksum updates are left as is, since they don't
conflict with offloading.

a DLT_NULL interface. In particular:
1) Consistently use type u_int32_t for the header of a
DLT_NULL device - it continues to represent the address
family as always.
2) In the DLT_NULL case get bpf_movein to store the u_int32_t
in a sockaddr rather than in the mbuf, to be consistent
with all the DLT types.
3) Consequently fix a bug in bpf_movein/bpfwrite which
only permitted packets up to 4 bytes less than the MTU
to be written.
4) Fix all DLT_NULL devices to have the code required to
allow writing to their bpf devices.
5) Move the code to allow writing to if_lo from if_simloop
to looutput, because it only applies to DLT_NULL devices
but was being applied to other devices that use if_simloop
possibly incorrectly.

opening a device, devfs_open needs the file descriptor to install its
own fileops. Failing to pass the file descriptor causes the vnode to
be returned with the regular vnops, which will cause a panic on the
first read or write because devfs_specops is not meant to support
those operations.
This bug caused a panic after exec'ing any set[ug]id program with
fds 0..2 closed (i.e., if any action had to be taken by fdcheckstd, we
would panic if the exec'd program ever tried to use any of those
descriptors).
