Nicira extension OXMs are documented in meta-flow.h. I guess you're
looking for these:
/* "tun_src".
*
* The IPv4 source address in the outer IP header of a tunneled packet.
*
* For non-tunneled packets, the value is 0.
*
* Type: be32.
* Maskable: bitwise.
* Formatting: IPv4.
* Prerequisites: none.
* Access: read/write.
* NXM: NXM_NX_TUN_IPV4_SRC(31) since v2.0.
* OXM: none.
* Prefix lookup member: tunnel.ip_src.
*/
MFF_TUN_SRC,
/* "tun_dst".
*
* The IPv4 destination address in the outer IP header of a tunneled
* packet.
*
* For non-tunneled packets, the value is 0.
*
* Type: be32.
* Maskable: bitwise.
* Formatting: IPv4.
* Prerequisites: none.
* Access: read/write.
* NXM: NXM_NX_TUN_IPV4_DST(32) since v2.0.
* OXM: none.
* Prefix lookup member: tunnel.ip_dst.
