Arnd Bergmann 9f7276ce82 ipv6: ila: select CONFIG_DST_CACHE
[ Upstream commit 83ed7d1fe2d2d4a11b30660dec20168bb473d9c1 ]

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.
