Hi,
This patch allows FT_NONE items to be built into filter expressions
(i.e. testing for their presence or absence rather than comparing with a
value) using the Apply|Prepare a Filter menus. What drove me to add
this was having to type in !tcp.analysis.out_of_order.
Does this seem reasonable?
Regards,
Martin
