geneve gtpu vxlan vxlan-gpe: VRF-aware bypass node
Bypass node MUST NOT intercept a packet if destination IP doesn’t match
a local address. However IP address interpretation depends on the VRF,
hence bypass node must take that into account.
This patch also factors-out common VTEP management and checking code.
Type: improvement
