The tc flower filter rules are used to control E-switch from the application side. In order to gain garanteed rule hardware offload the skip_sw flag should be specified while applying the rule. Some tc rules is rejected by kernel if skip_sw flag is set by design. Currently this regards VXLAN tunneling rules only, which are applied to special VXLAN virtual devices.
Albeit these rules should be applied with no skip_sw flag set the kernel tries to perform hardware offload. If kernel succeeded the in_hw flag is set in rule properties and application may check this flag to get know whether the applied rule is actually hardware offloaded.
