The proto field in struct rte_gre_hdr from lib/net lacks endianness annotation.
This triggers a sparse warning (from OVS dpdk-latest build):

/home/runner/work/ovs/ovs/dpdk-dir/build/include/rte_flow.h:1095:22:
error: incorrect type in initializer (different base types)
/home/runner/work/ovs/ovs/dpdk-dir/build/include/rte_flow.h:1095:22:
expected unsigned short [usertype] proto
/home/runner/work/ovs/ovs/dpdk-dir/build/include/rte_flow.h:1095:22:
got restricted ovs_be16 [usertype]
