Umm, actually, you can't possibly be aware of that, as there currently
*aren't* two capture syntax forms.

The syntax listed in the Ethereal man page is the correct one for
*display* filters; display filters are used for, well, filtering the
display, as well as for searching for packets, but they're not used for
filtering captures.

Try that - it's the *only* syntax for capture filters.

BGP is TCP port 179, so the tcpdump-syntax capture filter is

	tcp port 179
