macsec: Detect if Rx skb is macsec-related for offloading devices that update md_dst
Can now correctly identify where the packets should be delivered by using
md_dst or its absence on devices that provide it.
This detection is not possible without device drivers that update md_dst. A
fallback pattern should be used for supporting such device drivers. This
fallback mode causes multicast messages to be cloned to both the non-macsec
and macsec ports, independent of whether the multicast message received was
encrypted over MACsec or not. Other non-macsec traffic may also fail to be
handled correctly for devices in promiscuous mode.
