Hi Pablo,

I've bisected a link error to this patch:

net/netfilter/nft_reject_inet.o: In function `nft_reject_inet_eval':
nft_reject_inet.c:(.text+0xa7): undefined reference to `nf_send_unreach6'
nft_reject_inet.c:(.text+0x10c): undefined reference to `nf_send_unreach6'
nft_reject_inet.c:(.text+0x138): undefined reference to `nf_send_reset6'

Unfortunately I don't immediately see what went wrong, maybe you
can spot it.
