My randconfig builds came across an old missing dependency for ILA:
ERROR: "dst_cache_set_ip6" [net/ipv6/ila/ila.ko] undefined! ERROR: "dst_cache_get" [net/ipv6/ila/ila.ko] undefined! ERROR: "dst_cache_init" [net/ipv6/ila/ila.ko] undefined! ERROR: "dst_cache_destroy" [net/ipv6/ila/ila.ko] undefined!
We almost never run into this by accident because randconfig builds end up selecting DST_CACHE from some other tunnel protocol, and this one appears to be the only one missing the explicit 'select'.
From all I can tell, this problem first appeared in linux-4.9 when dst_cache support got added to ILA.
