Add support for equal-cost multipath IP.
To minimise path disruptions, this implements recommendations made in RFC2992 -
the hash-threshold mechanism to select paths based on source/destination IP
address pairs, and inserts multipath routes in the middle of the route table.
To enable multipath distribution, use:
sysctl net.inet.ip.multipath=1
and/or:
sysctl net.inet6.ip6.multipath=1
