> encapsulation
>
> The new testpmd set vxlan-tos-ttl command is added. It allows to specify tos
> and tll fields for encapsulation IP header.

> IPv4 VXLAN outer header:

> testpmd> set vxlan-tos-ttl ip-version ipv4 vni 4 udp-src 4
> udp-dst 4 ip-tos 0 ip-ttl 255 ip-src 127.0.0.1

> udp-dst 4 ip-tos 0 ip-ttl 255 ::1 ip-dst ::2222
> eth-src 11:11:11:11:11:11 eth-dst
> 22:22:22:22:22:22

> Note: ip-ttl parameter corresponds the nop_limits field for IPv6.
