The ofw_reg_to_paddr() in this file is the powerpc OF_decode_addr()
formerly added in 812403402e. However,
the latter function in turn was based on the sparc64 counterpart I
previously added in 2b2250b149.

With the current implementation of if_bridge(4), bridge_enqueue()
calls gif_transmit() only. Ensure it stays that way so that the
expectations in both drivers are either met or changed accordingly.

The code added in c89c8a1029 in order
to compensate possible misalignment caused by prepending the IP4/6
header with an EtherIP one got broken at some point by a rewrite of
gif(4). For better or worse, 8018ac153f
relaxed the alignment of struct ip from 32 bit to 16 bit, though. As
a result, a 16 bit offset of the IPv4 header induced by the addition
of the 16 bit EtherIP one no longer is a problem in the first place.
The alignment of struct ip6_hdr currently is even only 8 bit, making
it even less problematic with regards to possible misalignment.
Thus, remove the code for handling misalignment in in{,6}_gif_output()
altogether again.
While at it, replace the 3 bcopy(9) calls in gif(4) with memcpy(9) as
there's no need to handle overlap here.

These bits are obsolete since 58aa35d429.
This change reverts part of 9ba2b298df as
well as effectively bd3d9826d7, i. e. the
SBus-related modifications. This also gets rid of a nasty hack required
as bus_{read,write}_N(9) doesn't really fit bus_space_subregion(9).

The original idea behind calling into the bridge driver was to have the
logic deciding whether tuning is actually required for a particular bus
timing in a given slot as well as doing the sanity checking only on the
controller layer which also generally is better suited for these due to
say SDHCI_SDR50_NEEDS_TUNING. On another thought, not every such driver
should need to check whether tuning is required at all, though, and not
everything is SDHCI in the first place.
Adjust sdhci(4) accordingly keeping sdhci_generic_tune() a bit cautious
still.

As per https://lists.freebsd.org/archives/freebsd-scsi/2023-July/000257.html
move to the modern uintXX_t. While here also migrate u_char to uint8_t.
Where other kernel interfaces allow, migrate u_long to uint64_t.
No functional changes intended.

Send an ICMPv6 echo request packet with multiple IPv6 fragment headers.
Set rules to pass all packets, except for ICMPv6 echo requests.
pf ought to drop the echo request, but doesn't because it reassembles
the packet, and then doesn't handle the second fragment header. In other
words: it fails to detect the ICMPv6 echo header.

With 'scrub fragment reassemble' if a packet contains multiple IPv6
fragment headers we would reassemble the packet and immediately
continue processing it.
That is, we'd remove the first fragment header and expect the next
header to be a final header (i.e. TCP, UDP, ICMPv6, ...). However, if
it's another fragment header we'd not treat the packet correctly.
That is, we'd fail to recognise the payload and treat it as if it were
an IPv6 fragment rather than as its actual payload.
Fix this by restarting the normalisation on the reassembled packet.
If there are multiple fragment headers drop the packet.

As of pytest 7.4 it no longer walks all the way to the root directory
of the file system to find conftest files. As a result we don't find /
usr/tests/conftest.py, and don't load atf_python. That in turn causes
atf_python tests to fail.
Explicitly set the confcutdir, as advised by the pytest changelog.

The network and address fields were sometimes truncated for netstat -i
without -W, and often much too wide for netstat -i with the -W option.
Fields such as normal packet counts often overflowed. As a result,
columns didn't line up, and large white spaces made it harder to
follow a line across the display. Change the code to compute the
required field sizes for network, address, and various packet counts.
Hoist the code to format network and address into a subroutine that
can be called twice, once to measure the required field widths,
and once to emit the values. Use separate field widths for input
and output packets, byte counts, and error and drop counters.
These are left at defaults (the preceding values) with the -h
option, in which case the fields have a limited total width.
An extra space is included between the Network and Address, which
otherwise seemed too close.
Change the mention of -W with -i in the man page to say that most
field widths are computed dynamically in this case.
