EAPoL destination address

The MKA packets are transported over EAPoL with a multicast destination MAC address. At some point, it may be needed to have the MKA have a point-to-point connection to a peer node over a Layer 2 multihop cloud. In this case, the EAPoL destination MAC address can be set to the peer MAC address. This forces the MKA to traverse multiple nodes and establish an MKA session with the specific peer.
