You can do like the followings:

f0 = dp.ofproto_parser.OFPMatchField.make(
    ofproto_v1_2.OXM_OF_ETH_TYPE, 0x800)
f1 = dp.ofproto_parser.OFPMatchField.make(
    ofproto_v1_2.OXM_OF_IPV4_SRC,
    int(netaddr.IPNetwork('192.168.8.1').ip))

actions = [dp.ofproto_parser.OFPActionSetField(f0),
           dp.ofproto_parser.OFPActionSetField(f1),
           dp.ofproto_parser.OFPActionOutput(1, 1600)]
        

IIRC, with OVS:

- you can't set eth_type
- you need a match for IP if you set ipv4_src.
