Key for a IPv4 GRE Tunnel.
Key for a IPv6 GRE Tunnel We use a different type so that the V4 key hash is as small as possible.
Union of the two possible key types.

GRE_TUNNEL_TYPE_L3 |
L3 GRE (i.e.
this tunnel is in L3 mode)

GRE_TUNNEL_TYPE_TEB |
Transparent Ethernet Bridging - the tunnel is in L2 mode.
|
GRE_TUNNEL_TYPE_ERSPAN |
ERSPAN type 2 - the tunnel is for port mirror SPAN output.
Each tunnel is associated with a session ID and expected to be used for encap and output of mirrored packet from a L2 network only. There is no support for receiving ERSPAN packets from a GRE ERSPAN tunnel in VPP.
