Openflow IMO by nature is built to do complex matching, and for example for typical 12-tuple it is 750-4000 entries max in switches, but you go to l2 only matching which was possible at moment i tested, on my experience, only on PF5820 - you can do L2 entries only matching, then it can go 80k flows. But again, sticking to specific vendor is not recommended.
It would be possible to implement a general forward to controller policy and then upload matching on MAC address only as a offload strategy. You would have a different device doing the layer 3 stuff. The OpenFlow switch just adds and removes vlan tagging based on MAC matching. Regards
