To make sure I've understood this correctly: in previous versions of the spec,
If-None-Match options carried a payload, now they don't, so that code can be
removed.

But there is no way to filter on packets containing If-None-Match options
because there are no fields for them now. Shouldn't the option type itself be a
field that can be filtered on?
