 cases

The only thing this breaks is adding IPv6 routes via ioctl. Previously they would be automatically appended to form multipath routes but this no longer occurs. Changing to netlink or use iproute2 and using NLM_F_APPEND gets around this. This basically what David Ahern said earlier but I wanted to make it clear the default ioctl behaviour has changed.

Understood. I have to try the best option first. I'll look at
regressions if they happen.
