Here is a proposal to add the support of ECMPv6. The previous patch
from Vincent against iproute2 can be used, but a little other patch is needed
too:


If the kernel patch is approved, I will submit formally the patch for
iproute2.

Here is an example of a command to add an ECMP route:
$ ip -6 route add 3ffe:304:124:2306::/64 \
	nexthop via fe80::230:1bff:feb4:e05c dev eth0 weight 1 \
	nexthop via fe80::230:1bff:feb4:dd4f dev eth0 weight 1

Comments are welcome.

Regards,
Nicolas
