 usage of vxlan-netmap
 	 -o : overlay interface name
 	 -i : internal interface name
 	 -s : source vtep address
 	 -v : vni-vlan-mcastaddr mapping



 ethtool -K ixgbe0 rxvlan off txvlan off
 ethtool -K ixgbe1 rxvlan off txvlan off
 
 gcc -g vxlan-netmap.c -o vxlan-netmap -lpthread
 sudo ./vxlan-netmap -o ixgbe0 -i ixgbe1 -s 10.0.1.2 -v 1-10-239.0.0.10 -v 2-20-239.0.0.20

Packets including vlan id from a internal interface are encapsulated with a VNI which is configured by -v options, and transmited to vxlan overlay network from an overlay interface. specifying vlan id 0 means untaged packet.

• show commands
