Re: [PATCH net-next v5 1/2] net/sched: cls_flower: remove unions from fl_flow_key

When creating a flower classifier with an ipv4 address the
flow_dissector has both FLOW_DISSECTOR_KEY_IPV4_ADDRS and
FLOW_DISSECTOR_KEY_IPV6_ADDRS bits set in used_keys.
This happens because ipv4/ipv6 fields are a union and
FL_KEY_SET_IF_MASKED() will interpret either being set as both.

Removing the unions fixes this behavior without needing special handling
for union fields.

Jiri, this change is fine right?
