I've started with this, first item i am working on is to change
struct set to pass in struct expr *key instead of datatype+len to make
the original expression (meta iifname for example) available to the
linerize parts so we can stash this info in the udata.
For "typeof(meta iifname) . mark" case the parser will generate a concat
expression, and, since these keep the original expr around we can
iterate over that list to get back the original expressions.
For the normal 'type' case, i think we can simply use a dummy
constant expression to serve as a container for the data type.
What do you think?
