Add vxlan-bypass feature to IP4 forwarding path
Added vxlan-bypass feature which can be enabled on the underlay
interface which receive VXLAN packets to accelerate VXLAN decap
processing. The CLI to enable it is:
set interface ip vxlan-bypass <interface> [del]
With this feature enabled on an interface, there is an overhead for
non-VXLAN packets at about 13 clocks per packet.
The API is created to support vxlan-bypass for both VXLANoIPv4 and
VXLANoIPv6. With this change, vxlan-bypass is only implemented for
IPv4 forwarding path.
