Traffic / captures with 802.1q vlan tags in them fail
to show up at all in etherape. Having multiple modes
for displaying VLAN-tagged traffic would be nice:
* collapsed mode: vlan tags ignored, all traffic
displayed as usual (everything collapsed into one
* filtered mode: a VLAN tag is specified as part of
the filter, and only that VLAN is displayed.
* multi-graph mode: one graph is created per VLAN
tag... perhaps as a separate window, perhaps all
within the same window.
