A current Linux should accept the anycast address without any issues. Did
you have a look at the ICMP packets that get exchanged during Neighbour
Solicitation?
All Brocade devices I have under my administration do not handle IPv6
Neighbour Discorvery correctly (sad...), so maybe the RX8 is also buggy.

If you have a gateway that handles ND correctly Linux accepts that just
fine, so I don't think that you need any Kernel tweaks.
