[PATCH net-next 0/6] flower: validate control flags

[Asbjørn Sloth Tønnesen]

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_no_unsupp_control_flags
- 8 drivers using flow_rule_no_control_flags
- 11 drivers using flow_rule_match_no_control_flags

Asbjørn Sloth Tønnesen (6):
  flow_offload: add flow_rule_no_unsupp_control_flags()
  nfp: flower: fix check for unsupported control flags
  flow_offload: add flow_rule_no_control_flags()
  net: prestera: flower: validate control flags
  flow_offload: add flow_rule_match_no_control_flags()
