It is the same. What you are providing to ofproto/trace is a flow key:
Either the bit is present, or it is not. The mask (+/-) is only
determined to be relevant depending on the flow table so it doesn't
make sense for you to provide it. So, if the datapath dump says the
flow must have the new bit set, and must not have est, must not have
inv, must have trk (ie, +new-est-inv+trk), then this is equivalent to
saying that only the new and trk bits are present (ie, new|trk). The
rest of the bits are implied to be zero if you do not specify them.
