moved on to GRUB, so this is OBE now. If someone creeps up to work on it,
it could become a port.

were sometimes propagated using M_COPY_PKTHDR which actually did
something between a "move" and a "copy" operation. This is replaced
by M_MOVE_PKTHDR (which copies the pkthdr contents and "removes" it
from the source mbuf) and m_dup_pkthdr which copies the packet
header contents including any m_tag chain. This corrects numerous
problems whereby mbuf tags could be lost during packet manipulations.
These changes also introduce arguments to m_tag_copy and m_tag_copy_chain
to specify if the tag copy work should potentially block. This
introduces an incompatibility with openbsd which we may want to revisit.
Note that move/dup of packet headers does not handle target mbufs
that have a cluster bound to them. We may want to support this;
for now we watch for it with an assert.
Finally, M_COPYFLAGS was updated to include M_FIRSTFRAG|M_LASTFRAG.

Note that the original RFC 1323 (PAWS) says in 4.2.1 that the out of
order / reverse-time-indexed packet should be acknowledged as specified
in RFC-793 page 69 then dropped. The original PAWS code in FreeBSD (1994)
simply acknowledged the segment unconditionally, which is incorrect, and
was fixed in 1.183 (2002). At the moment we do not do checks for SYN or FIN

It really has nothing to do with supporting block sizes of 2^64.
