commit 475747a19316b08e856c666a20503e73d7ed67ed upstream.
Omit rx_use_md_dst comment in upstream commit since macsec_ops is not
documented.
Cannot know whether a Rx skb missing md_dst is intended for MACsec or not
without knowing whether the device is able to update this field during an
offload. Assume that an offload to a MACsec device cannot support updating
md_dst by default. Capable devices can advertise that they do indicate that
an skb is related to a MACsec offloaded packet using the md_dst.
