AggregateLength(I<KEYWORDS>)

=s analysis

sets aggregate annotation based on packet length

=d

AggregateLength sets the aggregate annotation on every passing packet to the
packet's length, plus any length stored in the extra length annotation.

Keyword arguments are:

=over 8

=item IP

Boolean. If true, then only include length starting at the IP header. Default
is false.

=back

If IP is true, then packets without a network header are pushed onto output 1,
or dropped if there is no output 1.
