1009bd1b0d Explicitly emphasize a facet of m_pullup() that some people seem to 
frequently forget. i.e. that you can not keep using pointers to
within the old chain.

7ac139a904 add m_copyup function.. This can be used to help make our ip stack less 
alignment restrictive, and help performance on some ethernet cards which
currently copy the entire packet a couple bytes to get the packet aligned
properly...

76f80df62e As I've been pointed out by Andrew Gallatin, there are some 
network interface cards smart (or twisted?) enough to be able
to calculate a TCP/UDP checksum for a packet fragmented by the
host CPU.  Therefore the paragraph on the case has been revised.

238d9c5975 Reformat the list of essential mbuf fields according 
to the nice style used in ifnet(9).
This includes specifying field types, starting descriptions
with a capital letter, and ending them with a full stop.
Improve the language a bit, as well.

da72b9983c Add missing descriptions of macros M_ALIGN and MH_ALIGN. 
Remove a reference to the defunct macro M_COPY_PKTHDR;
document the new functions m_dup_pkthdr() and m_move_pkthdr(),
and the macro variant of the latter, M_MOVE_PKTHDR().

7b2fd1831f Add more markup to the mbuf(9) manpage. This includes: 
- tagging plaintext "mbuf", "mbuf cluster", and "mbuf chain"
  with .Vt (variable type) since all of them are ways of managing
  data, i.e., they can be seen as data types;

- using .Vt/.Va instead of .Li (literal) where appropriate;

- tagging plaintext words that actually refer to function arguments
  with .Fa.

be82a0bc5a Use .Va, not .Fa, to refer to structure members. 
mdoc(7) contains an ambiguous statement on the issue,
but our mdoc(7) police's opinion is solid.
