ipv6: Revert "ipv6: Allow non-gateway ECMP for IPv6"
This reverts commit edd7ceb78296 ("ipv6: Allow non-gateway ECMP for
IPv6").
Eric reported a division by zero in rt6_multipath_rebalance() which is
caused by above commit that considers identical local routes to be
siblings. The division by zero happens because a nexthop weight is not
set for local routes.
Revert the commit as it does not fix a bug and has side effects.
To reproduce:
# ip -6 address add 2001:db8::1/64 dev dummy0
# ip -6 address add 2001:db8::1/64 dev dummy1
Fixes: edd7ceb78296 ("ipv6: Allow non-gateway ECMP for IPv6")
