Because, unlike some other pages, e.g. the Download page, it has only
one section, so the links at the top, which take you to various sections
on the page, don't do anything interesting (unless your browser window
is *really* short, so that the links *and* the table don't show up on
the same screen, in which case that link will scroll forward to show you
the top of the table).

I suspect those answers apply to all the BSDs, except for 802.11, where
you can do raw 802.11 "monitor mode" captures with the Cisco Aironet
card if you have FreeBSD 4.6 or later.

(The other free-software BSDs will probably eventually support raw-mode
802.11 captures on at least some cards, and FreeBSD will probably
eventually support it on more cards as well.)
