If a packet arrives on a tunnel port and is again transmitted on a tunnel
port, the packet needs to be encapsulated.
Eg:
Sample flow which arrives on a tunnel port and gets encapsulated again.
eth(src=00:15:5d:ae:b7:b1,dst=ff:ff:ff:ff:ff:ff),in_port(5),eth_type(0x0806),
arp(sip=192.168.1.12,tip=192.168.1.78,op=1,sha=00:15:5d:ae:b7:b1,tha=00:00:00:00:00:00),
tunnel(tun_id=0x5b88,dst=192.165.226.191,src=192.166.255.253,tos=0,ttl=63,
geneve({class=0x104,type=0x80,len=4,0x11680100}),flags(key))
actions:set(tunnel(tun_id=0x5b88,dst=192.165.226.190,ttl=64,
geneve({class=0x104,type=0x80,len=4,0x1680100}),flags(df|csum|key))),5,4
