Subject: Re: [PATCH net v5] net/ipv6: Add anycast addresses to a global hashtable

I'll follow this email with a new patch using ifacaddr6 instead of
creating a new struct. I ended up using fib6_nh.nh_dev to get the net,
instead of adding a back pointer to idev.  It seems that idev was
recently removed in lieu of this, so if this is incorrect, please let
me know. Hopefully, I got the locking correct.
Thanks,
Jeff
