This driver currently doesn't support any control flags. Use flow_rule_match_has_control_flags() to check for control flags, such as can be set through `tc flower ... ip_flags frag`. In case any control flags are masked, flow_rule_match_has_control_flags() sets a NL extended error message, and we return -EOPNOTSUPP. Only compile-tested.
