[P4-dev] storing field_list_calculation into a metadata field

Hi all,

is there any way to store the hash of a fields list (so a field list 
calculation) into a metadata field for further matching into a table?

The signature of the primitive action "modify_field" does not accept a 
field list as src parameter. Could please someone point out if there was 
any specific rationale for not allowing such thing?

Note: I still refer to the old specification (ver 1.0.2).

Best,
Salvatore
