xt_cluster for IPv6

[Valentin Vidić <vvidic@xxxxxxxxxxxxxxxxxxxxxx>]

Hi,

I would like to try xt_cluster for IPv6 but not sure how
to do the equivalent of ARP rewrite:

  arptables -I OUTPUT -o eth1 --h-length 6 \
            -j mangle --mangle-mac-s 01:00:5e:00:01:01

Is it possible to rewrite Neighbor Advertisement packages
somehow?
