Why?  That's the wrong type for something that you want to filter on, as
it doesn't have a value assigned to it.

Does filtering on

	cotp.type == CR

not find packets of type CR?  If it does, why is cotp.type.CR needed
(other than saving 3 characters in the filter expression - you can
reduce that to one character with

	cotp.type==CR

)?  If it doesn't, that's a bug.
