Initial L2 LISP support
This introduces support for layer 2 overlays with LISP. Similarly to L3, all tenant packets to be encapsulated are captured by an interface, but the mapping (layer binding) instead of being between an L3 VRF and a LISP VNI, it is between and an L2 bridge domain and a VNI. At a high level, this results in two important properties: 1) the source and destinations of all packets flooded in the bridge-domain are mapped via the LISP control plane and the replies are converted into data-plane tunnels tracked via a LISP specific source/dest L2 FIB 2) All packets reaching the interface and matching a source/dest L2 LISP FIB entry are L3 (IP4/6) encapsulated. This is solely a unicast feature, therefore at this time ARPs are not handled in any special way. Change-Id: I0b7badcd7c6d5166db07d4acd2cc4ae7fba3e18e Signed-off-by: Florin Coras <fcoras@cisco.com>
