  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.
