Subject: [PATCH net-next v3 0/4] flower: validate control flags

I have reviewed the flower control flags code.
In all, but one (sfc), the flags field wasn't
checked properly for unsupported flags.

In this series I have only included a single example
user for each helper function. Once the helpers are in,
I will submit patches for all other drivers implementing
flower.

After which there will be:
- 6 drivers using flow_rule_is_supp_control_flags()
- 8 drivers using flow_rule_has_control_flags()
- 11 drivers using flow_rule_match_has_control_flags()
