The exact endianness does not seem to matter, because the tunnel id is just used as a lookup key for the VLAN group's tunnel hash table, and the value is not interpreted directly per se. Moreover, rhashtable_lookup_fast treats the key argument as a const void *. Therefore, there is no functional change associated with this patch, just one to silence "make W=1" builds.
