nft add rule ip6 f i meta l4proto ipv6-icmp icmpv6 type nd-router-advert
<cmdline>:1:50-60: Error: conflicting protocols specified: unknown vs. icmpv6
add icmpv6 to nexthdr list so base gets updated correctly.

NB: This is STILL not correct.
nft add rule ip6 f i meta l4proto ipv6-icmp icmpv6 type nd-router-advert
gets listed as
icmpv6 type nd-router-advert
because post processing removes the l3 dependency.
However, "icmpv6 type nd-router-advert" uses dependency
ip6 nexthdr icmpv6
which isn't the same as meta l4proto icmpv6.
I suspect nft should always generate implicit l4 dependencies
via meta in the ipv6 case, what do others think
(and not autoremove 'nexthdr' check)?
