Why does ipfix need to un-wildcard fields?

I don't understand the change in compose_output_action__().  It adds
the ECN bits to the mask but I don't see anything there that depends
on those bits.

In do_xlate_actions(), why do OFPACT_SET_VLAN_VID and
OFPACT_SET_VLAN_PCP have new dependencies?  They do not read the
fields that they add to the mask.
