        net: fib_rules: allow to delete local rule
    
        Allow to delete the local rule and recreate it with a higher priority. This
        can be used to force packets with a local destination out on the wire instead
        of routing them to loopback. Additionally this patch allows to recreate rules
        with a priority of 0.
    
        Combined with the previous patch to allow oif classification, a socket can
        be bound to the desired interface and packets routed to the wire like this:
    
        # move local rule to lower priority
        ip rule add pref 1000 lookup local
        ip rule del pref 0
    
        # route packets of sockets bound to eth0 to the wire independant
        # of the destination address
        ip rule add pref 100 oif eth0 lookup 100
        ip route add default dev eth0 table 100
