You can use the Match API to set fields
https://github.com/osrg/ryu/blob/master/ryu/ofproto/ofproto_v1_3_parser.py#L1290-L1528.
But I generally try to avoid it, I would recommend you store your
match in a dict and then create Match objects from it right before you
send your flows:
from ryu.lib.packet import ether_types
from ryu.lib.packet import in_proto as inet
kwargs = dict(in_port=1, eth_type=ether_types.ETH_TYPE_IP,
ipv4_src='10.0.0.1', ipv4_dst='10.0.0.2',
ip_proto=inet.IPPROTO_UDP, udp_dst=5555)
match1 = parser.OFPMatch(**kwargs)
kwargs['in_port'] = 2
match2 = parser.OFPMatch(**kwargs)
Happy Hacking!

Mobile security can be enabling, not merely restricting. Employees who
bring their own devices (BYOD) to work are irked by the imposition of MDM
restrictions. Mobile Device Manager Plus allows you to control only the
apps on BYO-devices by containerizing them, leaving personal data untouched!
