Openvswitch uses function from NET_IPGRE_DEMUX module.
Add Kconfig dependency to fix following compilation errors:

Well, that works if CONFIG_INET is enabled, but if I disable that
kconfig symbol and then rebuild, this is what happens:
net/openvswitch/vport-gre.c: In function 'gre_tnl_send':
net/openvswitch/vport-gre.c:179:2: error: implicit declaration of function 'iptunnel_xmit' [-Werror=implicit-function-declaration]

It looks like config bug, I am getting config warning msg with config
you mentioned.
scripts/kconfig/conf --silentoldconfig Kconfig
warning: (OPENVSWITCH) selects NET_IPGRE_DEMUX which has unmet direct
dependencies (NET && INET)
warning: (OPENVSWITCH) selects NET_IPGRE_DEMUX which has unmet direct
dependencies (NET && INET)
----
anyways after discussing it with Jesse, I am going to add config
option for OVS-GRE which depends on INET and NET_IPGRE_DEMUX.
Thanks.
