Microsoft's Network Monitor lets you specify either a capture length, or
"Full".  It might be nice to have a special value that means "don't
limit my capture" in the "Capture Properties" spin box for capture
length, which would currently set the max packet size to 65535 (but it
might be nice to have "wiretap" let you not specify a capture length
and, on those platforms where you have to make a call to *set* the
capture length, just not make that call if no capture length was
specified).

This would, I think, mean not making that field in the "Capture
Preferences" dialog box be a spin box; the spin box is somewhat nice in
that it can limit you to values between the minimum and maximum (it's
currently not set up to limit you to values at or above the minimum, but
I'll be checking in a change to do that), but maybe there's some way to
let it be either a number or a special value.

It might also be nice to have it default to "no limit", as "snoop" and
Network Monitor do, at least for those of us who deal a lot with
protocols above the transport layer.
