Take a look at netdev_tnl_ip_build_header(…), for example.

Subject: [ovs-discuss] IPv4 address support for port configuration in OVS 2.8.0
version
Hello All,
I had recently downloaded the OVS 2.8.0 version code and was performing the
code walkthrough for ovs-vsctl command handling for adding port to bridge. I
see that structures related to port configuration takes only IPv6 address.
Hence kindly let me know whether we will be able to set the interface of a port
in a bridge with IPv4 remote and local IP.
ovs-vsctl set interface <bridge:pdn-port> type=gre/rte
option:remote_ip=172.20.1.1 option:local_ip=172.24.1.0
Code snippet under concern is
OVS 2.4 version
----------------------
/* Configuration specific to tunnels. */
struct netdev_tunnel_config {
bool in_key_present;
bool in_key_flow;
ovs_be64 in_key;
bool out_key_present;
bool out_key_flow;
ovs_be64 out_key;
ovs_be16 dst_port;
bool ip_src_flow;
bool ip_dst_flow;
ovs_be32 ip_src;
ovs_be32 ip_dst;
uint32_t exts;
uint8_t ttl;
bool ttl_inherit;
uint8_t tos;
bool tos_inherit;
bool csum;
bool ipsec;
bool dont_fragment;
};
OVS 2.8 Version
----------------------
* Configuration specific to tunnels. */
struct netdev_tunnel_config {
bool in_key_present;
bool in_key_flow;
ovs_be64 in_key;
bool out_key_present;
bool out_key_flow;
ovs_be64 out_key;
ovs_be16 dst_port;
bool ip_src_flow;
bool ip_dst_flow;
struct in6_addr ipv6_src;
struct in6_addr ipv6_dst;
uint32_t exts;
bool set_egress_pkt_mark;
uint32_t egress_pkt_mark;
uint8_t ttl;
bool ttl_inherit;
uint8_t tos;
bool tos_inherit;
bool csum;
bool dont_fragment;
enum netdev_pt_mode pt_mode;
};
