You can finx all the syntax that you can use with OFPMatch at:

http://ryu.readthedocs.org/en/latest/ofproto_v1_2_ref.html#flow-match-structure

I guess that there various ways to do the above. For example, you
could install flows with a match eth_dst of a host (for packets to
the host) and flows with a match eth_src of the host (for packets from
the host). Then you could aggregate them.
