    ipv6: ila: select CONFIG_DST_CACHE · 83ed7d1f
    Arnd Bergmann authored
    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.
